Troubleshooting a Suzuki P0118 Code can be stressful for car owners as this code indicates a sensor-related problem. The P0118 code is associated with the engine coolant temperature sensor circuit, which detects the engine’s temperature and communicates the data to the PCM (powertrain control module). The code is triggered if the PCM detects a value lower than -40ºF or higher than 4.90v. Causes of the P0118 code include an open or shorted circuit, a damaged or failed sensor, or a failed PCM. To repair the issue, car owners must identify the cause and take necessary action to fix it. The most common solutions for the P0118 code are to improve the opening in the sensor signal circuit, repair the short to VREF or system power, repair the opening in the sensor ground circuit, replace the sensor, or replace the PCM.
