chuckb Posted December 14, 2005 Share Posted December 14, 2005 I have a cel that just came on on my 95 ES. Car still runs fine. I went to autozone and discount auto to get it checked, but both said they can only check 96+ any other ideas. what do you guys think it is? car has 92k miles. I'm guessing it's an 02 sensor....

blake918 Posted December 14, 2005 Share Posted December 14, 2005 I went to autozone and discount auto to get it checked, but both said they can only check 96+ :uh: ← Your car is OBD II. Just go back to AutoZone, and tell them it's a 1998 model. ;) They always say '96 because that's when most (or all?) cars became OBD II. The ES was OBD II since '94. AutoZone read many codes on my old 94 ES. I second the O2 sensor guess! Quote Link to comment Share on other sites More sharing options...

Toysrme Posted December 14, 2005 Share Posted December 14, 2005 Ya. Just be sure you're using the OBD-II compatible DLC. (DLC3 behind the fuse box cover I do believe). The 1mz-fe's are the world's first compliant OBD-II engines, but oddly still had Toyota's OBD-I DLC1 & DLC2. Wierd, wild *BLEEP* man.

chuckb Posted December 15, 2005 Author Share Posted December 15, 2005 thanks for the tips guys. here's the results. first 02 sensor it looks like this sensor is easy to change. is there anything special I need to know, or do I just unbolt/unplug the old one and vice versa?

chuckb Posted December 18, 2005 Author Share Posted December 18, 2005 thanks again guys. I am getting ready to install new sensor and I just realized I don't know which one is "sensor 1 in bank 1" is it the one on the front of the motor or the one on back near firewall?

chuckb Posted December 18, 2005 Author Share Posted December 18, 2005 I did more searching and found out it's the one near fire wall. of course :cries: no biggie though, I already changed it. I just had to cram my arm in behind the motor. it took me longer to get the plug unplugged because it was hard to get 2 hands on it. Quote Link to comment Share on other sites More sharing options...
chuckb Posted December 21, 2005 Author Share Posted December 21, 2005 so after the 02 sensor was replaced, about a week later, now another CEL. this time it's the 0401 EGR code. do I need to get a new egr valve or egr valve actuator or are they the same part?

Toysrme Posted December 21, 2005 Share Posted December 21, 2005 Take it off & clean it, the actuator, the electronic harness for it & make sure the vacuum lines are OK. Quote Link to comment Share on other sites More sharing options...
chuckb Posted December 22, 2005 Author Share Posted December 22, 2005 Take it off & clean it, the actuator, the electronic harness for it & make sure the vacuum lines are OK. thanks-saw your response on CL too. so do I just clean it with carb cleaner, does that usually work? also, is the actuator part of the egr when you buy a new oem egr, or is that a separate part?
