What it means
The control module detects voltage above the expected range in the control pilot indicator control circuit. This indicates a fault in that monitored circuit; the effect on charging depends on the vehicle.
At a glance
- Usually lights the check-engine light
How it works
The control pilot indicator control circuit operates an indicator associated with charging. The control module monitors circuit voltage, and P0E3E sets when voltage is higher than expected, which can result from a short to battery positive, an open indicator, or a poor connector connection.
Common causes
Most likely first.
- Wire shorted to B+
- Open lamp
- Connector pins corroded - high contact resistance
Symptoms
- Charge status indicator shows fault
- Charging may not start or interrupts
- Slower-than-expected charge rate
How to diagnose it
- Record freeze-frame data and check live control-pilot indicator circuit data alongside the charging complaint.
- Inspect the indicator and connector for an open lamp, corrosion, loose terminals, or wiring damage.
- Check the circuit for a short to battery positive and inspect the harness for chafing against powered wiring.
- Test the indicator for an open circuit and check connector contact condition using the manufacturer’s procedure.
- Measure circuit voltage and continuity under specified conditions and compare with the manufacturer’s specification.
Common fixes
- Repair wiring shorted to battery positive in the control pilot indicator circuit.
- Repair loose or corroded connector terminals.
- Replace an open or failed indicator.
- Verify the circuit and charging operation after repairs.
Can I keep driving?
Charging may fail to start, stop unexpectedly, or proceed more slowly than expected. Avoid depending on this indicator to verify charge status, and stop charging if the equipment or vehicle reports an abnormal condition.
A code shows where the control module detected a fault, not always which part failed. Check the causes in order and confirm with a test before replacing parts. Have several codes? Check them together
This is a generic code: it means the same on every make. The car’s maker may add more detail in its own service information.
