P2E17Intermediate Shaft Selection Actuator Position Sensor Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2E17 tells you the position signal of the intermediate shaft selection actuator is stuck at the bottom of its range or below it. On the bench this usually turns out to be a signal line touching ground, a dead reference supply, or a sensor whose output stage has failed. No manufacturer documents P2E17 publicly. As a reference point, GM's 2023 dual-clutch TCM tables call a rod position sensor low (P2833) when pulses are missing with less than 2000 mV at the pin or when the duty cycle drops below 8 %, Type A. CARB requires transmission inputs to be checked for values outside their range. Start with the connector at the gearbox, then the reference voltage, then the sensor. The matching high fault is P2E18; for the main gear selection actuator the low fault is P2E12.
- What you may notice
- MIL and transmission warning
- Limp mode with limited gears
- Code returns at once after clearing
- Likely causes
- LikelySignal line shorted to ground
- PossibleSensor reference voltage missing
- PossibleOutput stage of the position sensor failed
- RareSignal wire interrupted (on sensors that then read low)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
