P0097
PPowertrainIntake Air Temperature Sensor 2 Low (Bank 1)
What does this code mean?
Severity : LowP0097 indicates low voltage on the intake air temperature sensor 2 circuit, bank 1. Depending on the engine, this sensor is often located after the turbocharger or intercooler, or in the intake manifold. Low voltage usually means an unrealistically high temperature reading, often caused by a short to ground.
Symptoms
- Check engine light on.
- Possible slight loss of performance.
- Higher fuel consumption.
- Often no noticeable symptom.
Possible causes
- Faulty intake air temperature sensor 2.
- Wiring shorted to ground.
- Corroded or damaged connector.
- Engine control module fault, which is rare.
Diagnosis and repair
- Inspect the sensor connector and wiring.
- Compare the reading in live data with actual air temperature.
- Measure sensor resistance with a multimeter against temperature.
- Check the signal wire for a short to ground.
- Replace the sensor or repair the wiring, then clear the code.
