What should the voltage be on a p0118 Chevrolet?
What should the voltage be on a p0118 Chevrolet? When the coolant is warm, the sensor resistance is low. The signal voltage is pulled down a greater amount; therefore, the PCM senses a low signal voltage (high temperature). At normal operating temperature, the voltage should measure about 1.5-2.0 volts at the PCM. P0118 CHEVROLET More Information. Which is p0118 engine coolant temperature sensor high input?
