Greetings,
I have the A4SGC00C MY02 WRX ECU and I am trying to dig up the correct location to disable the rear o2 CEL, as I am going to run a LM1 wideband with Bosch sensor and remove the OEM o2.
I have posted my ROM in the USDM 02 collection if anyone wants to help!
Here's where I have found the relevant o2 codes :-
P0037 - Rear O2 Sensor Heater Control Circuit Low **
0x00002EBC
0x00007D2C
0x00007DEA
0x00007DF6
0x0002DBB5
P0038 - Rear 02 Sensor Heater Control Circuit High **
0x0002DBAD
P0137 - Rear O2 Sensor Low Voltage **
0x0001E7B4
P0138 - Rear O2 Sensor High Voltage **
did not find this
P0139 - Rear O2 Sensor Circuit Slow Response **
0x0002DAF1
Which one do I overwrite with the 05 00 00 sequence? Or do I disable all of them for the rear o2? Which one is the correct location for the P0037 as I found 5 locations?
Any help appreciated as my wideband is being delivered today or tomorrow!
Thanks,
Gethin.
