P0115 CHRYSLER 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 is the cause of P0115?

Diagnostic trouble code (DTC) P0115 stands for “Engine Coolant Temperature Sensor Circuit.” This code sets when the powertrain control module (PCM) detects erratic or irrational input signals coming from the engine coolant temperature (ECT) sensor circuit.

Where is the water temperature sensor located?


Zitat von Youtube: Now some of the early models had two sensors in the same location. But you're looking for the one with the two wires on it and it's down here under the egi valve. And it's coming at the view.

Where is the radiator temperature sensor located?

However, the coolant temperature sensor is often located right on the cylinder head or engine block. You will find it installed conveniently on a plastic hose on the coolant’s inlet. Some automobiles come with more than one coolant temperature sensor.

What are the symptoms of a faulty coolant temperature sensor?

What Signs May Signal Your Coolant Temperature Sensor May Be Failing?

  • Poor Fuel Economy. …
  • Irregular Temperature Readings. …
  • Black Smoke from Your Exhaust. …
  • Your Engine is Overheating. …
  • Your Check Engine Light is On.
  U0001 CHRYSLER code


Is there a fuse for coolant temperature sensor?

In general, there are not many. Depending on the vehicle’s model year, there will either be a wire fused with voltage to the instrument cluster or a sensor that detects resistance to ground with the temperature sensor recording its position at the touch of a button on the dashboard.

Can you drive without a coolant temperature sensor?

It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicle’s coolant sensor is a critical component used by the engine management system. It directly affects, cooling and fueling of the engine and therefore affects how the engine performs.

How do you check a coolant temperature sensor?

Ohmmeter-Testing

  1. Start with a cold engine. …
  2. Attach an ohmmeter, across the sensor’s terminals.
  3. Measure the sensor’s resistance and record the reading.
  4. Reconnect the sensor wiring connector.
  5. Start and run the engine for two minutes, then shut the engine off.
