P2E02
Moderate Severity (Level 3)Gear Lever Position Sensor A Circuit Low
P2E02 usually means gear Lever Position Sensor A Circuit Low.
Can you still drive with P2E02?
⚠️Short-distance driving is usually OK, but have this diagnosed within a week to prevent further damage.
Typical repair cost: $80 – $1200
Severity Level 3 — Moderate
This code indicates a moderate issue that may affect vehicle performance and fuel economy. Continued driving is possible in most cases, but prompt diagnosis and repair are recommended to prevent further damage.
Common Symptoms
- Check Engine Light illuminated
- Engine performance reading zero or abnormally low
- Diagnostic trouble code (DTC) stored in module memory
- Fault may be intermittent — code may clear itself and reappear
- Reduced vehicle functionality related to the powertrain/engine system
Possible Causes
- Failed engine sensor or actuator — internal resistance has increased, outputting a signal lower than specification
- Damaged wiring or corroded connector in the powertrain/engine system circuit introducing high resistance
- Short to ground in the powertrain/engine system signal wire — wire chafed through, signal voltage pulled low
- Loose or oxidized ground connection for the engine sensor or actuator — 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 ($37-109 at shop, free at auto parts store for basic scan)
- Visually inspect the powertrain/engine system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $119 diagnostic fee at shop)
- Test engine sensor or actuator with a multimeter at the connector — compare readings to factory service manual specs. If out of spec, replace engine sensor or actuator ($80-1200)
- Check the reference voltage supply to engine sensor or actuator — should be steady 5V (or 12V) — if low, trace back to PCM/BCM voltage regulator ($168-451 if module repair needed)
- Perform a voltage drop test on the ground side of the powertrain/engine system circuit — more than 0.1V drop means a bad ground that must be cleaned/repaired ($89-215 at shop)
