I get an engine light that comes on when the temp gets to middle and not all the time, dont matter what speed etc but it wont come on before the temp gets to the middle zone..

Today while re routing my vac hoses I noticed the one thing I have not done yet, the PCV valve is bad, would a bad PCV cause an engine light to come on?

Did you look under the passenger side carpet and look at your ecu and count the blinking lights?

 

no not yet, I read u have to jump the wire harness or something too.. or noso I just need to turn the key on and count the blinking lights

No jumping of amy harness, just count the lights.

 

My bets 1 light

 

probably o2 sensor or iat sensor.

 

so what I go out there pull back the carpet turn the key to on (dont start the car) and then count the flashing lights on the ecu?

youshouldusepuncuation. yes lift the carpet in the pass. side and your ecu is there with a little window. turn the key to the on position and count how many times it blinks. leave the key on for a minute, the blinks will repeat themselves. count them, come back and post how many blinks, and someoneone will help you

 

must have been one... cause it was 1 flash...... 1 flash..... 1 flash....... 1flash and kept going over 100 lol..

I take it if it was a different number it would have been more like 1234......1234..... etc

Dave

 

correct. it blinks the code, pauses, blinks code... and so on. i'm pretty sure 1 is the o2 sensor. use search to find the code descriptions and make sure. search this forum only for "ecu codes" and you'll find a thread that has them.

 

Its ur o2 sensor take it out and clean it if your poor or just buy a new one.

 

na I can buy a new Denso for like 20.00, looks like I have something else to do tomorrow

Dave

 

if you can afford it get the removal tool also. it makes it alot easier. if it is stuck on you might also get the motor hot to remove it. i destroyed one and had to take my manifold off to get it out.

 

I have the oxy socket allready!

 

so whts the easy way to do it let the car run for 10 min or so to heat it up then hit it with the oxy sensor socket???

Dave

 

hey, what would you use to clean the o2 sensor? i ran seafoam through my car 3 months ago and lots of carbon came out of the exhaust, so im guessing my o2 sensor is covered in it also. would i just use carb cleaner? its a relatively new o2 sensor. my mileage ranges from 28-35 city per gallon

 

for the price of an oxygen sensor for our cars, ifu are going to pull it, just replace it..
