Laymans terms

This means that the car's computer detected that the temperature sensor in the charger is reading too high. It's like when a thermometer shows a temperature that's too hot.

Explanation

The car's charging system has a sensor that measures the temperature of the charger. If the sensor reads a temperature that's too high, it triggers this code.

Technical description

The P1C87 code indicates that the Universal Charger Extension Control Module has detected a high voltage or resistance in the circuit for the AC Charger Temperature Sensor. This could be due to a faulty sensor, wiring issues, or a problem with the control module itself.

Symptoms

• Charging system warning light on the dashboard

• Inability to charge the vehicle

• Possible overheating of the charging system

Common Causes

• Faulty AC Charger Temperature Sensor

• Wiring issues or poor connections in the sensor circuit

• Malfunctioning Universal Charger Extension Control Module

Glossary

OBD-II: On-Board Diagnostics, a standardized system for vehicle diagnostics.

Multimeter: An electronic measuring instrument that combines several measurement functions in one unit.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connections to the AC Charger Temperature Sensor.

• Test the AC Charger Temperature Sensor for proper operation.

Repair procedures

• Replace the AC Charger Temperature Sensor if faulty.

• Repair or replace damaged wiring or connections.

• Replace the Universal Charger Extension Control Module if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools
