O2 Sensor Computer Code?????

Hey all -

I'm new to the diesel world and have problems with my 1999 F-250. The check engine light has been on and off for a few months now and I finally have been able to have it read. When it is on, the truck runs like crap, and feels like it's not running on all of it's cylinders. Sometimes it will come on and stay on, other times it will come on for a few minutes and go away and run fine.

The code that came up is P0136 02 Sensor Circuit Malfunction (Bank I Sensor 2). Can anyone interpret this for me and tell me what I need to fix?

I originally thought the problem stemmed from the CPS recall that was not done, but since the code came up O2 sensor - I don't think that's whats wrong. Any and all help is really appreciated. Thanks!

No such code for a '99 7.3L PSD is listed in my PC/ED (powertrain control/electronic diagnosis) manual. You probably either read it wrong, or else you used a scanner that won't properly read PSD diagnostic trouble codes (DTCs)

I glanced through all the DTCs for a '99 PSD, and didn't see any that included "bank 1 sensor 2". There were several that included "sensor circuit malfunction" but none seemed to fit your condition.

So give us an accurate DTC and maybe someone can interpret it for you.

If Action4478 is right, then:

DTC: P1316
Circuit: IDM
Problem: Injector circuit/IDM codes detected
Probable cause: Injector circuit failure/IDM codes detected

That means your scanner must be able to read injector driver module (IDM) codes to see exactly what is wrong. If that's where you got the "bank 1 sensor 2", then it's probably a problem with the under valve cover (UVC) wiring harness going to the injectors. Replace the wiring harness clip for bank 1 injector 2 and that should fix it.

"Hissing" in the exhaust system is caused by a closed or partially-closed exhaust back pressure valve (EPBV). Perfectly normal until the engine oil gets up to around 168° F.
