Check engine light code p0118 - 1998 Chevrolet Cavalier

SOURCE: 2001 Kia Optima

P1529 and P0720 does not seem to be understood.

P0715 means Input/Turbine Speed Sensor Circuit Malfunction.

P0118 means Engine Coolant Temperature Circuit High Input.

SOURCE: Code P0118 on Audi A4 - Related to Ignition Coil Problem?

Hi, the sensor on the engine (right at the rear end of the cylinder head) has two separate outputs. One drives the temperature gauge and the other provides data for the engine control unit. The output for the engine control unit is almost certainly faulty and the sensor will need to be replaced. It isn't an expensive item and's not time consuming to replace (1/2 hr) - so you could ask Audi to do it for you when they replace the ignition coils.
Hope that helps Matt..

SOURCE: no voltage at the engine coolant temperature

ever since 1995 you have to turn off useing a obd2 scanner, if you do not have one, you can go to any auto parts store and they will erase the code for free. by having the light still on the computer thinks it still has an error. good luck Toolman,

SOURCE: Wont pass emissions code p0118

This code indicates a high voltage from the ETC, the engine coolant temperature. Supposedly a high voltage means a low temperature. Try to disconnect/ reconnect the battery a few times; this should clear the code. If the code returns, it is most likely the sensor. This should have nothing to do with the emmisions. If that's the only code, then the emmisions problem could be catalytic converters, O2 sensors, fuel injectors, could need a tune up, etc... usually emissions problems have to do with poor fuel burn-off.

SOURCE: 97grand am code P0118 replaced ect sensor clear

Engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set.

The reference values given below are measured between ECM terminal 72 and ground...

When measuring input / output voltage be careful not to use ECM ground terminals. The ECM will enter fail safe mode once a malfunction is detected and the MI will light up.

Usually, P0118 is indicative of a bad temperature sensor, but doesn't rule out these other possibilities. If you're unsure of how to diagnose a PCM, do not attempt.
