Code P1119 GMC Description
The P1119 code for GMC vehicles indicates that the engine coolant temperature signal is out of range. This means that the Engine Control Module (ECM) is receiving a signal from the coolant temperature sensor that is either too high or too low for normal operating conditions. The engine coolant temperature sensor is a crucial component that measures the temperature of the coolant in the engine and sends this information to the ECM, which uses it to adjust fuel delivery and ignition timing for optimal performance.
Common Causes of P1119 GMC
- Faulty engine coolant temperature sensor
- Wiring or connector issues in the coolant temperature sensor circuit
- Low coolant levels or coolant leaks
- ECM malfunction
- Cooling system issues such as a malfunctioning thermostat
Symptoms of P1119 GMC
- Engine overheating
- Rough idle or stalling
- Poor fuel efficiency
- Check Engine Light illuminated
- Reduced engine power
How to Fix P1119 GMC
- Begin by using a diagnostic scanner to read the fault codes and confirm the P1119 code.
