How do you fix trouble code P0118?
What repairs can fix the P0118 code?
- Repairing or replacing the ECT connector.
- Repairing or replacing the wiring open circuit as necessary.
- Replacing the ECT with a new sensor.
What can cause a P0118 code?
The onboard diagnostic (OBD) code P0118 is an Engine Coolant Temperature Circuit – High Input malfunction. This code refers to the engine coolant temperature (ECT) sensor. The code is also set if the PCM determines that the ECT sensor resistance is out of specification.
What happens when your coolant sensor goes bad?
If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer. This will reduce fuel economy, and may hinder engine performance.
How does coolant temperature sensor work on Toyota p0118?
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.
What does the ECT code p0118 mean?
Code P0118 is the result of the ECT sensor indicating a high voltage input from the coolant temperature circuit. (typically over 4.7V) What Are the Symptoms of Code P0118?
Why does my 2002 Mini Cooper p0118 still come back?
2002 Mini Cooper S P0118 is still came back after I have replaced a PCM sensor. Does outside temperature relate to this problem where I have a bad outside temp TC (fluctuate reading on the gauge). Engine temp is reading normal (at the mid range). What should I do next to solve it.
What are the symptoms of a p0118 car accident?
Symptoms of a P0118 could include: Very poor fuel economy A no start condition Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring Illumination of MIL
