P0A92Hybrid Generator Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0A92 indicates that the generator of a hybrid system, the electric machine mainly used to convert engine power into electrical energy, does not reach the expected output, speed or torque. CARB requires manufacturers to describe how they monitor the generator so that faults preventing it from working are detected. FCA documents the code for the 2020 Jeep Compass and Renegade plug-in hybrids (bulletin 08-057-21): it appears together with drive motor phase current sensor codes, and the fix is a software update of the hybrid control processor and power inverter module. A turtle (limp home) lamp may accompany it. P0A90/P0A91 cover the drive motors; P0A3F and similar codes cover generator position sensing.
- What you may notice
- MIL and hybrid system warning
- Limp home (turtle) lamp, reduced power
- Reduced charging of the high-voltage battery
- Likely causes
- LikelyHybrid controller or inverter software needing update (documented by FCA)
- PossibleInverter phase current sensing fault
- RareInternal generator fault (winding, bearing, position sensor)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
