Re: wifes car cant get rid of CEL
 

if u have a scanner why don`t u plug it up and take it for a drive and check all the readings

Re: wifes car cant get rid of CEL
 

yes you only have bank 1, obdII ownes you :1. If you have a universal 02 sensor I would start there. If it checks out then do just like you would anything else when checking for running rich, fuel pressure, compression, tune-up, bluh bluh bluh.

friend has a scanner he let me borrow for a minute to scan code

Re: wifes car cant get rid of CEL
 

when i had the scanner hooked up i did datalog it and the reading was like .84 volts which is low but didnt drive it to see if it had full sweep or not getting 2 other o2's in a couple days so i will run checks of everything else till then

AND YES OBDII DOES OWN THE ---- OUT OF ME!!!!!!!

ok put an upstream and downstream o2 in it and still same thing. clean out fpr and reset ecu still lost any other sugg.

if your tps is reading wrong it might be adding to much fuel, you could also have a leaky injector, check your plugs for fouling

if your tps is reading wrong it might be adding to much fuel, you could also have a leaky injector, check your plugs for fouling it could also be the cat, its job is to burn the unburnt fuel, if its not firing it would give u rich reading on the downstream,

use a infered thermomiter to check the temp of the cat when it is hot, you should be about 40% hoter on the back side of the cat

Re: wifes car cant get rid of CEL
 

cant do that as i am trying to get the car through emmisions. it would have been no problem if they still did obd II cars through the tailpipe still but they hook it up to the diagnostic port now. thats why i am trying to fix it.

You can use the scan tool to erase the error code. I've used a Snap-On scan tool and it has the option.
