What does po117 mean?

What does po117 mean?

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).

Why is my car reading hot but not overheating?

If you find that you’ve got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.

What does the p0118 code on a coolant temperature sensor mean?

This data is sent to the ECM, which uses this data to regulate the air to fuel ratio, cooling fans, and ignition spark timing needed by the engine. Code P0118 is the result of the ECT sensor indicating a high voltage input from the coolant temperature circuit. (typically over 4.7V)

What temperature should a thermostat be set at in a car?

Some vehicles are equipped with a thermostat with an opening temperature of 180°F (82°C), whereas other vehicles use a thermostat that is 195°F (90°C) or higher. Before replacing the ECT sensor, be sure that the engine is operating at the temperature specified by the manufacturer.

Should I replace my ECM If I have error code p0118?

If the wiring checks ok you may want to consider replacing the ECM. For error code P0118, one or more of the below repairs may be needed to solve the underlying issue. For each possible repair, the estimated cost of repair includes the cost of the relevant parts and the cost of labor required to make the repair.

What is the resistance of an electric thermistor?

The ECT has a very high resistance when cold and low resistance when hot (see table). This type of thermistor is called an NTC (negative temperature coefficient), which is opposite to the situation with most other electrical components.
