How do I fix error P0117?

What repairs can fix the P0117 code?

1. Resetting the fault codes and perform a road test.
2. Repairing or replacing the ECT connector.
3. Repairing or replacing the wiring as necessary.
4. Replacing the ECT with a new sensor.

What is engine code P0117?

Code P0117 Definition Engine Coolant Temperature (ECT) Sensor Circuit has lower than normal voltage.

What does engine coolant temperature low circuit mean?

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. Once the PCM detects a signal voltage that’s lower than the normal operating range of the sensor, the OBD code P0117 registers in your vehicle’s memory.

Where is the ECT sensor located?

cylinder head
The ECT sensor is located in the left of the cylinder head and is connected to the Engine Coolant Temperature Sensor. Underneath the air intake pipe and behind the right cylinder head is where the Engine Coolant Temperature Sensor is located.

How is P0171 diagnosed?

How does a mechanic diagnose the P0171 code? Assuming that no other trouble codes exist, a mechanic may diagnose the P0171 code by checking the engine for vacuum leaks with a vacuum gauge and checking the fuel pressure with a fuel pressure gauge.

What does P2181 code mean?

Cooling System Performance
OBD-II Code P2181 is defined as a Cooling System Performance. The engine computer (PCM) monitors coolant temperature in the radiator (Radiator Coolant Temperature Sensor) and in the engine (Engine Coolant Temperature Sensor).

How do I test my ECT sensor?

Ohmmeter-Testing Start with a cold engine. With the ignition off, disconnect the wiring connector from the (ECT) sensor. Attach an ohmmeter across the sensor’s terminals. Measure the sensor’s resistance and record the reading.

Is it OK to drive with P0171 code?

It is okay to drive a vehicle with P0171 for a short period of time, but driving with this code for an extended period of time can overheat the engine and cause internal engine damage.

Can a bad O2 sensor cause P0171?

You probably know that the answer the questions is — no! A P0171 or P0174 lean code with an O2 sensor reading lean all the time mean — well, several things. The real problem may not be a bad O2 sensor, but possibly be an engine vacuum leak, low fuel pressure or dirty fuel injectors that are causing the engine run lean.
