Check Engine Light

whats mean dtc P1700 on zafira Z18XE.thanks

the emission lights could be comming on because your catalytic converter is not working right.

WITH MY 98 CAVELIER,I FOUND THE VACUMN LINE TO THE MAP SENSOR

OFF AND I REPLACED IT. NEXT I WENT THROUGH THE GEARS,AND THE E.T.S. LIGHT WENT OUT.THE ENGINE CHECK LIGHT WAS STILL ON AND I

NOTICED I HAD THE LARGE HOSE "CARB TO AIR FILTER OFF" I INSTALLED IT AND THE LIGHT WENT OUT."IT HAS A SENSOR IN IT" SUMMARY IS THE CAR RUNS FINE. LOUIEBELLSON@COMCAST.NET

HERES A BETTER SOLUTION...

instead of wasting money that you don't need to, puh the button on the side of your shift knob. That's the ETS button. It will turn it on.

Then I guess you didn't check everything...;) Could be internal...there's no telling really unless a professional trouble shoots it. Or unless you have recently had an reoccuring problems and can elaborate either on those or on any noises you've had with the car recently. That's all I have with the lack of info unless you want to try resetting the ECU which would involve you disconnecting the battery, pumping your brakes, letting it sit for 10-15 min then reconnecting and starting her up. Good luck.

Try disconnecting the battery for a minute or 2 and then re-connect. This sometimes clears the codes in the engine control modules.

The engine computer has detected a malfunction and set a code.

Under the hood on top of the left fender. Take it to your dealer to be analyzed or go to your local auto parts store and they should have an analyzer to test the module beneath the steerin column.

check for vacuum leaks unplug the negative post on the battery terminal for about 15 minites

I had this problem on and off for over 1 1/2 years, until finally, last year, my local Toyota dealer fixed it, under warranty, repairs totaled over $1200.00! My Rav 4 is a 2001, but apparently it is a large issue because I jst received a notice from Toyota stating that there has been a problem with the system that involves the "Check Engine" light, and they requested my car be brought in, if I hadn't already done so - contact a local dealer ASAP!

if there is a auto zone around you take your car there they will do a dyno test on it for free i had a problem with my car that the light would not go off and i had a lose hose that was causing the problem did you put fuel injector fluid in your car to make sure the fuel injector wasn't dirty?

obd 2 systems can be very complicated, and once the code is triggered, it will stay in the ecu til its erased, a friend of mine was running into the same problems it turned out to be her gas cap which wasnt tightened correctly, and threw the code and it stayed there til it was erased, try disconnecting your battery, and see if it clears. if Honda did the reapirs, take it back to them and make them fix it.

By the way, if you enjoy modding you car, like i do, the check engine light may come on after doing work on your car. For instance, today, i put a short RAM intake on my 1999 Honda Accord EX-L V6. After completing the install, i unplugged the sensors and turned on the car for a sec to let it know that it should recalculate the air intake. I then reconnected the sensors and turned the car on. I let it idle for a while so it could recalibrate. After doing all this, I realized the check engine light, or malfunction light was on. I understood that this was because i had been tinkering, and of course i didn't want to pay $80 for a diagnostic, which would turn off the light. What i could have done, is wait, and after 40 startups with no problem the light would have turned off. Alternatively, what i did was REMOVE THE NUMBER 13 FUSE FROM THE FUSE BOX ON THE PASSENGER DOOR FRAME FOR 10 SECONDS AND THEN REPLACE IT. THIS WILL MAKE YOUR MALFUNCTION/CHECK ENGINE LIGHT GO OFF BUT THIS IS NOT RECOMMENDED AND I DON'T TAKE ANY RESPONSIBILITY IF YOU RUIN YOUR CAR. THAT LIGHT USUALLY DOESN'T LIGHT UNLESS THERE IS A PROBLEM. IF THE LIGHT COMES BACK ON AFTER A WHILE YOU SHOULD TAKE YOUR CAR TO A QUALIFIED TECHNITIAN BECAUSE SOMETHING IS REALLY <EXPLETIVE>'ED UP!

get the CEL checked and fix the problem. Disconnecting the battery for 15 minutes will reset the light on an OBD1 vehicle.

if no one knows go to google.

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.

It is below the injection pump, in the back of the timing cover.

I have an 88 Ford Taurus L wagon and something like this is happening to me. The transmission is slipping in and out of overdrive and when it does the "check engine" like goes on briefly. I still have to have it looked at so I don't know about the code. But, my car did not just quit working right away. By the way, this problem just started last week and it does appear to be getting worse.

Disconnect the red battery wire then reconnect it.

Trouble code P0420 means: Catalyst Efficiency Below Normal (Bank 1)

When the Check Engine Light (CEL) comes on, it means something wrong was detected, either with emissions or performance. When this happens, the computer will have a diagnostic code in memory that can be retrieved with an OBDII scanner. Auto Zone will scan and retrieve the diagnostic codes free of charge.

Code 1618 indicates a failur in communications between the Engine Control Processor and the Automatic Trans-Axle Processor. The ECM / PCM stores the trouble info as freeze frame and the "Check Engine Lanp(MIL) will light. The MIL will be turned OFF after 3 on the 3rd trip cycle if the foult is no longer present. The freeze frame info will clear after 40 consecutive worm-up cycles have occurred wthout a foult.

Have it checked for trouble codes. You will then know what to diagnose. Check coolant level as well, look at the recovery tank to see if your level is up. ANOTHER THOUGHT Also, when you check the trouble codes, if nothing shows up you might want to put a volt meter on the battery. If the alternator can't keep up with the power that the blower is using you MIGHT be dropping below what the computer wants to see. Use a volt meter and check if the voltage drops below 13.5 VDC when the heater is turned on. You'll need to give the engine a little throttle, bring it up to around 1500 to 2000 RPM when you check the voltage level. If it's not maintaining voltage, it's probably the alternator. Have it checked by a reputable auto parts retailer such as Checker or Auto Zone.

after 1994 all cars sold in America had to be OBD 11 compliant which means you need to have the code reader plugged in and read the code or codes causing the light to be on. gas cap will do that. then simply erase the codes from the ecm. good news here is alot of auto parts places have the code reader and will do it free. autozone and orielly's are 2 that i know of here. good luck.. fyi i purchased a code reader from harbor freight tools for $35 dollars. everyone wants to use it now.

It could be a "slight" problem with the electronic sensors. If a "check engine" light is on, the computer has detected a problem with the sensors. You need to use a code scanner to detect the fault code.

buenas tarde

tengo un problema , tengo una captiva y me aparece estos codigos p0008 y p0017 , quiero saber que problema tiene mi vehiculo , gracias
