03 pt cruiser engine code p0440 comes on once a month?
Trouble code P0440 means:Evaporative emission control system malfunction

Answer . The code means you have a problem with the evaporative emissions system. Generally the cause is a loose gascap. Before spending money on diagnosis, make sure the cap is tight and have the code cleared. If the light comes back on, the system needs to be checked for leaks, faulty canister…,and/or vacuum valves.

Could be several things depending on how hard of a knock it is. Rod bearing, stuck piston ring, cracked piston, low oil and lifters chattering, fuel injector stuck. Any knock is usually serious and almost always expensive to fix.
There is a problem on the engine or transmission. One of the sensors sends a code to the computer and this code is store into the memory. You can use this information to fix the problem To find the errror you have to turn the ignition on and off 3 times. Chrysler calls this key dance ON-OFF-ON-…OFF-ON. The code with the problem will be display on the cluster. Write it down and check the code. (MORE)
You will need to pull the negative lead from the battery for 10 minutes.. Or you can just wait for a couple of days and it will reset on it's own, as long as you fixed the reason for it lighting in the first place.
If you need to turn off the light because it is screwing up your smog check, you can disconnect and then reconnect the battery (reseting the computer and turning off the light). The advice given to me was: "After you reset the computer, drive for 25 miles". In my experience the light always comes ba…ck on within 25 miles. For the purposes of passing your smog check, just head over there right after you set the light off. (Make sure your Idleing smooth) Note* This advice is for those who: 1. Know why their light is on, putting off repairs, or don't care. 2. Have scensor issues and several mechanics and can't get the light to stay off! 3. Are not legitimatley failing the smog check. Turning off the light won't help those who are. (MORE)

A P0440 code (GENERAL EVAP SYSTEM FAILURE) is typically one of two things... a huge evaporative system leak or a failed NVLD unit.. The evaporative system is the vapor side of your fuel system. Vapors need to be contained, stored and burned just like liquid fuel does. An on-board leak detection sys…tem tests for overall performance of the evap system at practically any time in one manner or another.. A leak could be as simple as a gas cap left loose. Actually, it takes a leak of almost this size to set a P0440. When fuel vapors can escape out the filler neck, they won't be stored in the vapor canister and a purge flow failure will result. This combines the two major components of the system (leak testing and purge flow) in failure mode, so the result is P0440.. The natural vacuum leak detector (NVLD) is the device that senses whether the system is air-tight and confirms purge flow testing. It's nothing more than a device that can sense a weak vacuum / low pressure condition in the evap system and then close an electrical switch to tell the PCM that all is well.. If the NVLD has a failed switch, it doesn't matter that the system may be completely alright... it still has the appearance of failure.. Start off looking for evaporative system leaks. The cap is the first stop. Check to see first if it was tightened properly. I like to lightly twist the cap counter-clockwise using just the spring built into the cap's top. If the cap is loose, it will come off using just this tiny bit of force. If it's been tightened, it won't.. If it seems tight, remove it and check the rubber seal on the cap for cracking. Cracks are a sure sign that it's leaking, but probably not enough to cause a P0440.. The vapor canister would be the next stop. It's under the truck, so inspect it for damage from road debris. A large (1/2" dia) hose connects the top of the canister to the NVLD unit. This hose typically cracks and falls off. A replacement hose runs less than $10.. If no leaks are found at this point, I'd recommend replacing the NVLD. It's the odd black plastic unit with two 1/2" hose ports on it and a single 3- wire connector . The type of leak needed to set your code needs either a huge leak or a failed NVLD. With no leak, this is all that remains in the vast majority of cases.. The exceptions? Very rarely, damage to the wiring harness can simulate a failed NVLD. Rodents can chew wiring practically anywhere and this little pigtail is no exception. The PCM (engine controller) has shown failure to sense the NVLD signal on rare occasions (I saw it one time). (MORE)
Simply stated; it is the most common code indicating a problem with your ECT (engine coolant temperature) sensor. In and of itself this is not a huge deal (read not expensive and easy self-repair). But do deal with it right away - it affects many other components. If it is allowed to provide invalid… inputs to the PCM (power control module - the "computer") for any length of time - it will produce a domino effect that will drive you nuts.. Having said all that - be sure that the sensor is not actually trying to tell you something important about the status of your engine. Does your temperature indicator on the instrument cluster appear to be at its normal position? (MORE)
It's an evaporative emission system leak. Usually kicked off when the gas cap is not secured after refueling. It will show up usually after the engine has cooled and restarted the next day.
Yes, they can. My wife's 2004 PT Cruiser was just diagnosed to have a broken engine mount.
Check fuse #18 (20amp, yellow) in the Power Distribution Center box under the hood. This fuse has a plastic pull-tab on it. It's used to control Ignition-Off Draw = IOD. The fuse is pushed in when you take delivery of the vehicle. The owners' manual explains that it's used to keep the battery from d…raining during extended storage. If it's blown, you will need to determine what caused it to blow. This 20a fuse won't blow unless you've added a load to the circuit or there is a component failure. It doesn't take much to blow the fuse, the addition of a stereo or alarm, or even the power window modification, if you wired it into that circuit. If you haven't added an additional load, and the vehicle self-tests check out OK, dealer service will need to diagnose the problem. (MORE)
P0551 power steering switch failure. Replace the power steering pressure switch.. \nThere is a switch that senses the pressure of the hydraulic fluid which reflects how hard it is working (e.g. like when turning at low speed or when stopped). It then opens the switch (which is normally grounded) an…d a wire to the powertrain controller senses that and increase the idle speed accordingly so the engine doesn' falter. Here is an exchange I had earlier with another owner about it.\n"The switch is located on the back side of the power steering gear. It is supposed to raise the idle speed when you are turning the wheels at low speeds when the system will require more pressure and thus otherwise drag down the idle. The wire to the switch is dark blue/light green (signal) and a black ground; and the signal wire goes to pin 45 of the powertrain control module. So you might check the connector at the switch and the connection to pin 45 of the controller, from pin 2 of the plug...\nAll I can add is that if you locate the two high pressure lines that run to the steering gear from the power steering pump you will find the switch right next to where those two lines connect to the gear. It no doubt just screws out and then install the new one. The manual says that you remove the electrical plug, lifting the locking tab carefully. Then it says to use a crowfoot wrench and extension to remove the old one. The steering fluid will run out so be prepared to clean catch it, and be ready to screw in the new one to minimize loss. If you catch the fluid in a clean pan you car reuse it. The torque spec with a crowfoot wrench is 12 foot pounds and you have to be careful not to exceed the limit or you may ruin the fine hydraulic threads on the steering gear and then you have a potentially expensive problem. So if you can't get a crowfoot that fits the sensor (when you buy the replacement you can see what the size it) and don't have an extension and a torque wrench you may want to let the shop do it. Make sure the electrical plug is in place with the locking tab engaging the tab on the switch. Refill the power steering reservoir. Start the engine and then turn the steering wheel from lock to lock several times to bleed the air from the system. Use only Chrysler power steering fluid if you loose some of it."\nI doubt it has anything to do with the fluid, unless the code started right after that. If the wire seems OK, then the question is the switch stuck open (measure that) or is the pressure really too high when you are driving at normal speed or not even turning the wheel. That would have to measured with a gauge. (MORE)
What is the problem on a Chevy silverado half ton pick up truck when Service engine soon code p0440 light comes on?
P0440 indicates and evaporative system failure. Unless you are mechanically inclined take it to a good mechanic or Chevy dealer.

You probably have a misfire; \nHave it checked for codes. Most likely you need a tune up.
\nNot really, they are both a very poor automobile. Horrible ride, noisy engine, wide turning circle, and some of the most uncomfortable seats in any vehicle made. There are way better choices to spend your money on.
you have a leak on the sending unit (o-ring usually after a pump replacement) or a hose to the canister EVAP system

Not really feasible. The engine and transmission are removed as anunit out the bottom. You would need a way to lift the car highenough to get the engine out.
Yes But the valves will not hit the pistons. The only interference that can happen is valve to valve interference.
Protects, no. The only temp sensor is the coolant temp sensor. The car will run until the engine is ruined if allowed to continue overheating.
The P0440 code is for an EVAP system leak. This code sets when the vehicle's computer detects that the EVAP system cannot seal itself after running the onboard diagnostic test that it runs at random times once enable criteria has been satisfied. The problem could be something as simple as a loose ga…s cap or an inoperatve purge or vent solenoid or as complex as a wiring issue or as expensive as a powertrain control module (PCM) the vehicle's computer. Always perform a visual inspection of the EVAP system prior to replacing any parts, because guessing can get to be very expensive rather quickly. As I mentioned make sure the gas cap is adequately tightened and if you are somewhat mechanically knowledgeable follow all of the lines coming off the fuel tank to where they end paying close attention to good connections or any physical damage such as a crack, split or broken line.

What would cause severe engine power loss and the service engine light to come on in a 2001 PT Cruiser?
The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on,… too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.

It depends on what lights, did you turn on a switch, open a door, If they are dash warning lights, you have a malfunction.
Contact your closest Chrysler dealer (you will need the radio serial number and the PT Cruisers VIN) They will be able to provide the code for a small fee.
on a European model pt cruiser (USA domestic pt cruisers do not have this) if the radio loses power it goes into a security mode which requires a code to unlock and resume normal function. this is intended as a theft deterrent as the thief would not have the code your local dealer should be able to …supply the code as needed though they may be a small charge for this (MORE)
all European PT Cruisers have a radio unlock code that needs to be entered in the event the radio loses power. USA domestic PT Cruisers do not have a radio code
P0440 sets when the evaporative emission system large/medium leak monitor test fails. Normally meaning there is a leak in the system. This can happen from a loose or not sealing gas cap, solinoid valve not working or not sealing, or a brocken/cracked emission hose. Best bet is to do a visual inspect…ion of the evaporative emission system and replace anything that is broken or unhooked. If you can find anything take it to a repair shop and have a evap system leak test performed. Most new OBDII car can be forced to run the monitor test with a handheld scan tool with the correct software installed. (MORE)

Yes and no... It is classified as a non-interference engine because if the timing belt were to break while driving the pistons will not hit and damage the valves. However, with the dual overhead cam it is possible that the valves from the intake can strike the valves from the exhaust, and vise versa…. This has been known to happen, although typically only seen if the car was at high rpm when the belt broke. (MORE)
