How do I fix error P0117?
What repairs can fix the P0117 code?
- Resetting the fault codes and perform a road test.
- Repairing or replacing the ECT connector.
- Repairing or replacing the wiring as necessary.
- Replacing the ECT with a new sensor.
What causes code P0117?
P0117 code indicates that the vehicle’s powertrain control module or PCM has detected a low voltage input from the engine coolant temperature (ECT) sensor 1. The low signal that the PCM detects from the ECT sensor can mean that the engine coolant is excessively hot.
What problems can a bad coolant temperature sensor cause?
Overheating engine The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.
What happens to the p0117 code when coolant is warm?
As the temperature of the coolant changes, the resistance of the sensor changes. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low. If the PCM detects a signal voltage lower than the normal operating range of the sensor then P0117 code will set.
What is the purpose of the p0117 ECT code?
P0117 ECT (Engine Coolant Temperature) Sensor Circuit Low Voltage: The purpose of this code is as a diagnostic check for a resistance corresponding to a very high engine coolant temperature. The check is enabled whenever the engine computer ECM (Engine Control Module) or PCM (Powertrain Control Module) is powered.
What causes the p0117 OBD-II trouble code?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0117 is the OBD-II generic code that indicates the engine control module (ECM) has seen the ECT sensor output go less than 0.14 Volts or more than 140°C (284°F). What causes the P0117 code?
What is the diagnostic code for engine coolant temperature?
Cost of diagnosing the P0117 code. P0117 is a diagnostic trouble code (DTC) for “Engine Coolant Temperature (ECT) Sensor Circuit Low Output Problem”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
