Does anyone know what these codes I am throwing.

P0606
The PCM has determined that an internal processor fault has occurred.

P0138
The PCM has determined that the input voltage from oxygem sensor 2 in bank 1 is too high for current operating conditions. (Oxygen sensor 1 is closest to the cyclinder head before catalytic converter. While oxygen sensors 2&3 are located further downstream and are typically mounted in or after the catalytic converter) (bank1 identifies the location of cylinder #1. while bank 2 identifies the cylinders on the opposite bank)

Its weird b/c it comes and goes all the time. Sometimes i can go for 3 weeks without a CEL and one day i'll start my car and its back on. IT NEVER comes on while im driving.

 

I deleted them with the code reader. They havent came back yet, and they usually dont for a few days or sometimes a few weeks.

 

yea, your PCM determined that one of the internal processors has caused a fault...

I kid, I kid..

honestly, I dont know what P0606 is... the fact that it turns on when you are driving rules out pretty much everything i was going to suggest, sorry!

 

are you using the o2 extended on the 2nd o2 sensor?

 

Yes im defenitley using the extender.

 

On the second O2 sensor though? If you put it on the 1st one it doesn't work correctly...

 

The first O2 sensor is actually a 0-5v wideband and is voltage dependent...you can not extended the harness

 

Um its not a wiring extension. Its a hardware extender that moves the sensor several inches out of the exhaust stream..

 

I do have the O2 extender on the S-pipe O2 sensor. I just threw the CEL again this morning it seems to only happen in the cold weather. Its been hot for about 3 weeks here in VA and i just threw the CEL a couple of days ago when the weather cooled down to around 50-60

 

ZPI do you think it could be this......I had O2 sim card hooked up before i went FI. Since i took the o2 sim off. I just reconnected the wires in the o2 sensor. Could that be throwing the voltage code on the sensor maybe. And what could i do to fix it

 

I would prefer not to buy a new o2 sensor.
