How do I fix code P0118?


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.

What does ECT sensor do?

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.

How do you fix engine code P0116?

What repairs can fix the P0116 code?

  1. Testing and replacing the thermostat.
  2. Testing and repairing any other ECT codes, such as P0115, P0117, P0118, P0119 or P0125.

What is P0115 engine code?

P0115 is the OBD-II generic code that indicates when the engine control module (ECM) reads the ECT sensor input go below or above the sensors expected range of 0.14 to 4.91 V (-40°C to 140°C -40°F to 284°F).

What can cause a P0118 code?

The onboard diagnostic (OBD) code P0118 is an Engine Coolant Temperature Circuit – High Input malfunction. When the engine has been running for more than a few minutes and the ECT is reading a less than freezing temperature, the PCM thinks there is a circuit fault and sets the P0118 code.

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.

What problems can a bad ECT sensor cause?

The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.

What can cause a P0116 code?

What are the Possible Causes of the P0116 Code?

  • Malfunctioning Engine Coolant Temperature Sensor.
  • Faulty or corroded ECT wiring or connections.
  • Engine overheating.
  • Engine temperature below specification.
  • An issue with the PCM, such as software in need of an update.

What is the cause of P0115?

As the temperature of the engine coolant changes, the sensor’s resistance changes on its ground signal to the PCM. If the engine is cold, the sensor’s resistance is high, but if the engine is warm, the resistance is low. An overheating engine is a possible cause of code P0115.

What is the code P0128?

The P0128 code means that the engine coolant is not getting warm enough, fast enough. In other words, there is a problem with the engine operating temperature not being reached within a certain amount of time. The Engine Control Module (ECM) determines this length of time based on ambient temperature.
