P2E17
Low Severity (Level 2)Intermediate Shaft Selection Actuator Position Sensor Circuit Low
P2E17 usually means intermediate Shaft Selection Actuator Position Sensor Circuit Low.
Can you still drive with P2E17?
⚠️Short-distance driving is usually OK, but have this diagnosed within a week to prevent further damage.
Typical repair cost: $30 – $200
Severity Level 2 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Poor cabin heat in winter
- Engine reading zero or abnormally low
- Temperature gauge stays on cold — engine runs rich in extended warm-up mode
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed IAT sensor — internal resistance has increased, outputting a signal lower than specification
- Damaged wiring or corroded connector in the intake air temperature sensor circuit introducing high resistance
- Short to ground in the intake air temperature sensor signal wire — wire chafed through, signal voltage pulled low
- Loose or oxidized ground connection for the IAT sensor — clean the ground and retest before replacing parts
- Low system voltage (weak battery or failing alternator) causing sensor reference voltage to sag
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($12-116 at shop, free at auto parts store for basic scan)
- Visually inspect the intake air temperature sensor wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $83 diagnostic fee at shop)
- Test IAT sensor with a multimeter at the connector — compare readings to factory service manual specs. If out of spec, replace IAT sensor ($30-200)
- Check the reference voltage supply to IAT sensor — should be steady 5V (or 12V) — if low, trace back to PCM/BCM voltage regulator ($183-426 if module repair needed)
- Perform a voltage drop test on the ground side of the intake air temperature sensor circuit — more than 0.1V drop means a bad ground that must be cleaned/repaired ($76-200 at shop)
