P0118 code chrysler, 7V) from the coolant temperature circuit

P0118 code chrysler, After collecting the coolant temperature information, the ECT P0118 - Engine Coolant Temperature Sensor Circuit High Input OBD-II Trouble Code Technical Description Engine Coolant Temperature Sensor Circuit High Input What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Honda, Toyota, Volkswagen VW, Mazda, Dodge, Ford, BW, etc. 7V) from the coolant temperature circuit. P0119 signals voltage that fluctuates outside the normal range. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. Although generic, the specific repair The trouble code may be referencing several underlying issues. Also, between the sensor and the Powertrain control module, you could have a voltage short. P0118: Engine Coolant Temp Sensor Circuit → High Input This code is thrown when the resistance coming from the coolant temp sensor does not change as the vehicle warms up. Aug 30, 2024 · Code P0118 Chrysler Description The P0118 code for Chrysler vehicles indicates that there is a problem with the engine coolant temperature sensor circuit registering a high voltage. What Does P0118 Mean? P0118 is a generic powertrain OBD-II code stored when the ECM detects that the Engine Coolant Temperature sensor signal is higher than expected—typically indicating a voltage above 4. The engine coolant temperature sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module Dec 27, 2025 · The P0118 code indicates a high voltage input in the Engine Coolant Temperature (ECT) sensor circuit, affecting engine performance and emissions. Nov 28, 2025 · This guide explains the meaning of P0118, common symptoms, causes, diagnosis steps, and reliable repair options. It is a general code, which means that it’s going to have the same meaning for the Chrysler 200 as it would any other vehicle. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. May 14, 2019 · CODE P0118 ENGINE COOLANT TEMPERATURE SENSOR 1 CIRCUIT HIGH DODGE JEEP CHRYSLERIf you have a Dodge, Chrysler, Jeep, or Fiat and you have engine light on and Apr 1, 2019 · This code is thrown when the resistance coming from the coolant temp sensor does not change as the vehicle warms up. Learn what Engine Coolant Temperature Sensor Circuit High means, location and how to repair. Nov 25, 2024 · Code P0118—Engine Coolant Temperature Sensor Circuit High Input is part of a diagnostic trouble code (DTC) family that involves circuitry issues with the ECT sensor. 9V. It also uses this information to protect the engine from overheating. P0118 indicates a high voltage condition, while P0117 is centered around low voltage. Chrysler Town and Country P0118 Symptoms P0118 is sometimes accompanied by noticeable symptoms. A faulty ECT sensor, wiring issues, or cooling system problems can cause the high voltage reading, requiring prompt diagnosis and repair. Aug 2, 2020 · Repair Information for P0118 Chrysler code. For example, you could have something as simple as a bad connection at the sensor or a bad ground circuit between the engine coolant temperature sensor and the Powertrain control module. The P0118 code indicates that your powertrain control module (PCM) observes a high voltage input (normally over 4. Make: Chrysler Code: P0118 Definition: Engine Coolant Temperature Sensor Circuit High Description: The Engine Coolant Temperature (ECT) Sensor is a variable resistor that functions as a normal two wire, 5-Volt sensor. The main function of the engine coolant temperature (ECT) sensor is to monitor a variation in the temperature of the engine coolant. What does this mean? OBD2 Code P0118 Chrysler definition: The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. The engine control module (PCM) uses this information to determine how much fuel to use to keep the engine running properly. ). What causes OBD-II fault code P0118? The Engine Coolant Temperature Sensor measures the temperature of the coolant going through the engine. The Powertrain Control Module (PCM) supplies the ECT Sensor with a 5-Volt reference and a filtered ground (return) circuit. The PCM monitors Mar 31, 2019 · P0118 is a common OBDII trouble code. These symptoms include failure to start, rough idle, misfiring, decreased fuel economy, and the service engine soon light. .
