P2E13: Gear Selection Actuator Position Sensor Circuit High

The ECM detects a circuit high fault on the gear selection actuator position sensor. Reading cannot be used reliably for control.

Most likely causes

• Signal wire shorted to B+
• Open sensor
• Connector pins corroded - high contact resistance

What to check, in order

Start with the simplest. You can tick off each step.

1. Check the fluid level and condition
2. Check the sensor's ground and make sure the signal wire is not receiving voltage from another circuit.
3. Read the input and output speed in live data
4. Check the connector and wiring
5. Check for other related engine codes
6. Consult the manufacturer's procedure for the transmission

Good to know

• Repair difficulty: medium
• It can trigger limp mode.

What each character of P2E13 means

• P: Powertrain: engine and transmission
• 2: Generic code: same on every make
• E: Subsystem depends on the code range
• 13: Specific fault in that system

Frequently asked questions

Can I keep driving with code P2E13?

Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.

What causes code P2E13?

The most common causes are: signal wire shorted to B+; open sensor; connector pins corroded - high contact resistance.
