2001 sabb dash light on error codes po131/p0132
P0131 - O2 Sensor Circuit Low Voltage Bank 1 Sensor 1 (sensor is before the catalytic converter)
Possible causes- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
P0132 - O2 Sensor Circuit High Voltage Bank 1 Sensor 1
Possible causes- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
I am not really sure what is going on here with the same O2 sensor giving these lean and rich codes, if nothing else is apparent and the engine runs well you may have a defective O2 sensor.
Thanks i will change the o2 sensor i think also this is the main problem
the car runs fine but seems to be drinking a bit more gas than i should looks like bank 1 sensor 1 runs the high and low voltage to me
just need a diagram of the saab from a manual to see which is sensor 1 lol
It is the snesor beofre the catalytic converter. There is just the one before and one after the cat.
i can see two one upper from top one under that and the cam one in the middle
