Recently I replaced an O2 sensor, easier than I thought and cel hasn't come on again.
Here's what i have:
2007 Dodge Charger R/T (w/out track pkg)
Check engine light came on and the diagnostic code read 013a. After some research that code means "O2 Sensor 1/2 - Rich or Lean"
-Dodge dealership wasn't completely useless for this, but not that much help, after the reasearch I had already done I was far more knowlegeable on this one small issue than the guy I bought the part from.
Between the Haynes Guide and dealership "Sensor 1/2" means "Sensor 1 Bank 2" = post cat passenger side
Cost for O2 sensor from Dodge dealership = $55.00
Time to replace = 20min (with no prior experience doing this)
Research time spent = approx 2-3 hrs (Reading Haynes, forums, talking to other members, friends, mechanics, dealer etc)
Steps:
1. Buy Haynes guide - invaluable, but really costs less than $50 and VERY worth it
2. Buy correct O2 sensor from dealer
3. MAKE SURE EXHAUST IS COOL BEFORE WORKING ON!!!!!!
4. Follow Haynes guide for replacement (uninstall = unplug, unscrew and reverse steps to install)
DONE!
Sidebar: I have a jack and jackstands, but I saw yesterday that Autozone sells these ramps that you can drive your ride onto, seems a lot better, costs about $50/ramp I think. (plus you can buy the sled to lay on, def on my xmas list this year :bigthumb: )
The Haynes guide says that after you've replaced the sensor you are to reset the PCM, and calibrate some things (more on that below). To reset the PCM I opened the trunk, and opened the cover to the spare tire compartment where the battery is on the right. Used a 1/2" wrench to disconnect the NEGATIVE (that's very important) and left it for a min or so, then reconnected it. This clears the settings and allows the PCM to lean the O2 levels from the new sensor. It will otherwise base it's readings off the old sensor and you will definately get the CEL coming on again. (I was able to test and verify this as I had an oil change and asked the guy to clear the codes, afterwards I replaced the sensor, then the CEL came on, reset the PCM the following day and no CEL since)
After that's done (and you've reset your radio/XM stations) the Haynes guide instructs you to recalibrate things such as the Steering Angle Sensor (SAS) and any Power Up windows. There are instructions how to do these both HOWEVER on 2007 models it said that SAS must be recalibrated by the dealership - this affects the ESP. Dodge dealer also said that this is not necessary b/c it's just like changing a battery and you wouldn't recalibrate the SAS if you change a battery. I haven't recalibrated the SAS and haven't noticed any change in ESP, and I have def tested it
Well that's a long post for an easy fix. Hope it helps someone.
