Check Engine Light

It means that your alternator is on it's way out. Same thing happened to me on a Liteace.

When the bank has not enough funds in the relevant account or the account holder requests that the cheque is bounced (under exceptional circumstances) then the bank will return the cheque to the account holder. The beneficiary of the cheque will have not been paid. This normally incurs a fee from the bank.

It is very easy to reset the check engine light on a 2002 Volkswagen Cabrio. The negative battery cable can be taken off for one minute and replaced to reset the light.

auto elec tech need cost about 40 to 45 pounds

disconnect the battery for about 30 sec then reconnect it

OBDII-equipped ECUs can be "reset", which turns off the MIL light, but it also erases drive cycle data and inspection will not pass till data is collected again.

Drive cycle data is collected by running car in a particular pattern or just by driving it for a period of time, but if catalyst is bad -- light will come on as soon as data is collected.

Aftermarket catalysts are not "that" expensive nowadays -- if it is still the original one from factory -- just get it replaced. Or you can fill best gas you can find and add one of those "guaranteed to pass" snake oils -- I doubt it will help though.

Another possible bugger can be oxygen sensor (there are two, before and after catalyst) -- they often get ceramic tube broken inside (may "rattle" when removed, but sometimes it just has a crack and won't "rattle", but still broken). Those can be checked by looking at OBDII data for a sensor -- it should jump up and down (very fast, tens of Hz) from about 0.5V to about 0.95V for working sensor. OBDII scanner shows "samples" taken at a slow rate (1 Hz or so) -- so you want to observe readings for a while and to note max and min readings. Mechanic with oscilloscope will be able to tell if O2 sensor is good for sure.

light means there is a fault picked up by ecu.error code must be retrieved and analised.Once repaired the light will go off.

Found this ibn the web and it is about right:

1. Put key in ignition switch.

2. Press the reset button for the trip distance recorder while turning the ignition key to position 1 and continue holding till the word tESt appearsin the display.

3. Release and Press and hold the button again and A FLASHING "rSt" (reset) will appear in the window. WHILE IT IS FLASHING PRESS THE BUTTON AGAIN AND IT WILL READOUT 15500 MILES

With a scan tool.

Haynes manuals have the codes in them,according to how many times the chec engine light flashes.OR advance auto parts will scan it for FREE

Did you try key on, key off, key on, key off, key on, key of? It works on my 2000 Dodge Intrepid

The scan tool is call an OBD 2 .it stands for On Board Diagnostis. it scans codes for check engine light , or use it any time your car is not running good. the codes appear across the scan view, and it give code # and most time where problem is. use haynes manual if tool does,nt tell you the problem. it also comes with a comp.disc which has "ALL" the codes. this will make you a home mechanic. great thing to buy

the connection for the scanner is located just under the passenger dash. toward the front. it is a 12 point connection

Code 1406 is EGR Valve Pintle Position Circuit Error. As far as your EGR "pintle position" code is concerned. Your EGR valve is sticking or malfunctioning. Remove and CAREFULLY clean the EGR valve shaft and it's passages in the engine and reinstall with a NEW gasket. If this does not resolve the problem, replace the EGR valve.

P035x series codes indicate the PCM has detected a fault in the primary circuit of the ignition coil #x. For P0355, this indicates #5 ignition coil. The most common (by far) cause is a faulty ignition coil, but it can also be caused by a problem in the wiring or in the PCM itself.

Unplug the electrical connector at coil #5 and connect a 12V test light in place of the coil. With the test light in place, have someone else start the engine. If the test light blinks, you need to replace that coil and it's corresponding spark plug to correct the problem. In almost all cases, you will see the test light blink.

If test light does not blink:

If the test light does not blink, you may have another problem. With key on engine stopped, check for power at one terminal of the connector. If there is no power, you have either a broken wire or short to ground on that wire.

With engine running, check for ground at one terminal of the connector to the coil. Test light should blink. Steady on indicated electrical short to ground on that wire. Steady off indicates: open circuit or short to power or bad PCM. To test for short to power, check for 12v+ (or more than 1V+) on that wire.

There are pages and pages of theings that can turn the check engine ligth on, you need to have it checked for codes. Another way to look at it, there is only ONE reason for the check engine light to come on, that being, the computer has detected a problem. You don't NECESSARILY need to HAVE it checked, since you can do that yourself. Go to just about any auto parts retailer where you can borrow, rent our buy an engine code scanner. Some of the more helpful places will even help you plug it in and decide what it means if they aren't terribly busy, and if you can drive the vehicle to their parking lot. But in general, you'll need to use a code scanner to find out why the computer has turned on the light. It's just the computer's way of saying, "HEY! YOU... BEHIND THE WHEEL THERE! PAY ATTENTION TO ME!"

The problem is " P0172 System Too Rich - Bank No. 1 " That's going to be your oxygen sensor before the cat... it has gone bad. Replace it. http://www.fordf150.net/howto/eecvcodes.php

Trouble code P1155 means: A/F Sensor Heater Circuit Malfunction

Usally that means the battery has been disconnected within the last 10 starts

Check the gas cap, if it is off or loose between 1/4 to 3/4 tank of gas it will set a evap code, thus setting the check engine light. It will take awhile to clear the code and turn the light off

I suspect your hold switch on the shift lever might be bad..or ahs a broken wire.

what type of vehicle is it if GM product on the driver side fuse panel

remove battery cable for 1 min

Have vehicle scanned to determine problem and have codes cleared Auto parts store can do this

I don't believe you (as an operator) can "reset" the check engine light. A mechanic can probably reset it using the port that actually draws the code which caused the failure. When my check engine light came on, I did what the owners manual indicated and just tried a few more tanks of gas (manual indicated that a bad tank of gas might be the problem, or the gas cap might not be installed correctly). After a tank and a half, light went out and hasn't been back on since.

The check engine light on a BMW 525i is reset by pressing the trip reset button until the engine icon appears. The Check and DC buttons are used to navigate between menus and the trip button held to actual reset the selected error.

P0171 System too Lean (Bank 1)

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 a parts store 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.

The code 43 is an old two digit code that could mean numerous things. You need to have it checked with an obd scan tool to find out the four digit "p" code. example (p0301) is cylinder #1 misfire.

43 could be a misfire, a coil circuit problem, or a PCM power supply issue. That covers at least 7 "p" codes.
