What is code P0115?

What is code P0115?

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 would be the conditions that dtc P0115 engine coolant temperature circuit malfunction can be logged as a fault in the engine management system?

Error Code P0115 is described as an Engine Coolant Temperature (ECT) Sensor Circuit Malfunction. It’s detected when there is too high or too low a change in the voltage signals that this sensor sends to the PCM (powertrain control module, also called an engine control module or ECM).

How do you test a water temperature sensor?

Submerge your temperature sensor in the hot water and wait a few seconds to let your multimeter take a reading. Write down your reading so you can easily reference it. A hot water reading should give you around . 25 volts.

Can I drive with a bad coolant temp 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 know if your coolant sensor is bad?

If you notice more fluctuation in your engine temperature or it looks higher or lower than usual while you’re driving, it could be the engine coolant temperature sensor. In particular, if your engine doesn’t seem to be warming up as it typically does, you should have a mechanic take a look at your cooling system.

How do I know if my temperature sensor is working?

Troubleshooting a faulty temperature sensor steps: Check you are using the correct type of cable. Check for local heat sources affecting your readings. Check setup of your temperature controller/readout. Resolve out of range errors.
