This code indicates that the evaporative emission system heater control circuit is not functioning properly. The evaporative emission system is responsible for capturing and storing fuel vapors from the fuel tank and preventing them from escaping into the atmosphere. The heater control circuit is responsible for regulating the temperature of the evaporative emission system canister, which helps to reduce fuel vapor pressure and prevent fuel vapors from escaping.
Possible causes of code P069E:
- Faulty evaporative emission system heater control module
- Faulty evaporative emission system heater element
- Damaged wiring or connectors in the evaporative emission system heater control circuit
P059F - Intake Air Heater Sensor Circuit High
This code indicates that the intake air heater sensor circuit is not functioning properly. The intake air heater is responsible for warming up the air that enters the engine, which helps to improve fuel efficiency and reduce emissions. The intake air heater sensor monitors the temperature of the intake air and adjusts the operation of the intake air heater accordingly.
Possible causes of code P059F:
- Faulty intake air heater sensor
- Damaged wiring or connectors in the intake air heater sensor circuit
- Faulty engine control module (ECM)
