P0A36 is the general circuit code for the temperature sensor in the hybrid generator, the machine that is mainly driven by the engine to produce electricity. It covers faults the module detects on the sensor line without classing them as low, high or implausible. No manufacturer documents P0A36 publicly; Mitsubishi (2023 Outlander PHEV) monitors its generator coil sensor with the specific codes P0A37 to P0A39 instead. CARB 1968.2 requires circuit monitoring for hybrid components that can affect emissions. With the generator temperature unknown, the system cannot protect the windings, so it usually restricts generator output and series operation and shows a hybrid warning.
Medium severity. Can I keep driving?If the battery warning light comes on, you could get stranded. Turn off electrical accessories and go straight to a repair shop.
Symptoms
- Hybrid warning or check engine light
- Generator output or battery charging restricted
- Generator temperature missing or implausible in live data
Most likely causes
- Loose or corroded connector between generator and its control unit
- Damaged sensor wiring near the transaxle
- Generator coil thermistor failed (usually replaced with the generator)
- Faulty input in the generator control unit
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- It can trigger limp mode.
- It affects emissions.
What each character of P0A36 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- A: Hybrid or air and fuel
- 36: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0A36?
If the battery warning light comes on, you could get stranded. Turn off electrical accessories and go straight to a repair shop.
What causes code P0A36?
The most common causes are: loose or corroded connector between generator and its control unit; damaged sensor wiring near the transaxle; generator coil thermistor failed (usually replaced with the generator).
