P0152 O2 Sensor Circuit High Voltage (Bank 2, Sensor 1)
Same condition as P0132 but on bank 2. The upstream sensor reports a continuously rich condition or has a short to supply voltage.
Is it safe to drive with P0152?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyBank 2 running rich (leaking injector, high fuel pressure)
- PossibleSignal wire shorted to supply voltage
- Less likelyConnector pins corroded - high contact resistance
Symptoms
- Check engine light on
- Increased fuel consumption
- Possible rough idle or hesitation
- Failed emissions test
