P111E GMC code

What is the engine coolant temperature sensor?

What is a Coolant Temperature Sensor and How Does It Work? A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.

What is po111 code?

What Does the P0111 Code Mean? Diagnostic trouble code (DTC) P0111 stands for “Intake Air Temperature Sensor 1 Circuit Range/Performance (Bank 1).” This error code is logged when the powertrain control module (PCM) perceives the signal from the intake air temperature (IAT) sensor to be outside factory specifications.

What is a P0098 code?

What the P0098 code means. P0098 is the OBD-II generic code indicating the engine control module (ECM) has determined that the intake air temperature sensor 2 (IAT2) has an open circuit in the sensor circuit.

What problems can a bad coolant temperature sensor cause?

A faulty sensor can cause the fuel mixture to adjust. This causes the engine to shake or vibrate when the vehicle is at low speed and can even bring about strange behaviors, power losses, etc. Engines are highly sensitive, especially to inappropriate air-fuel mixtures at idle.

Where is a coolant temp sensor located?

In most cars, the primary ECT sensor (ECT sensor 1) is installed near the thermostat in the cylinder head or block or on the thermostat housing. A second coolant temperature sensor could be installed in another part of the engine, or in the radiator.

Can you clean an IAT sensor?

For that, you’ll need Iso-Propyl Alcohol, a clear plastic bag, and q-tips. So, in short, that’s what you can use to clean an IAT sensor.

How is P0128 diagnosed?

The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose.

How do I fix code P0118?

What repairs can fix the P0118 code?

  1. Repairing or replacing the ECT connector.
  2. Repairing or replacing the wiring open circuit as necessary.
  3. Replacing the ECT with a new sensor.
