Hey guys, sorry to ask this. i know its already here but i cant find it and im running out of daylight.

How do you read the check engine light codes in the ecu? iv read it numerous times but cant remember and my searching is failing me.

Flame all you want, im trying to check this before i drive home tonight. replacing O2 sensor now and want to see whats wrong before i leave!

In the diagnostics box, bridge TE1 and E1 with a paperclip for the 3vze. There is a label under the cover that shows their locations. Turn the key to run and count the flashes of the CEL. Here is a good link on the subject too.

Thanks for the reply!

Wow so what are the odds??
I stop by monument auto parts to pick up a new o2 sensor on my way home from work because i have never replaced mine, im having a weird idle problem and im about to hit 200k miles on what i think is the stock o2 sensor. Figure why not right? its a good time.
On my way home from the store my check engine light comes on for the first time since i have owned the truck! (eight years) Checked the codes this morning, looks like a code 25 and 26.

Now im not 100% sure on how to diagnose the code and what the sheets say about it but they can be caused by the o2 sensor. But i replaced the sensor, started it up and no CEL. What are the odds! I buy a new o2 sensor 20 minutes before mine gives out? 200k miles and i pick up a new one on on my last few miles! haha


Just thought it was pretty amazing so i wanted to share.
