Should a Temp control sensor have a ohm reading? | Boating ...

2012-08-27· Re: Should a Temp control sensor have a ohm reading? When making resistance measurements you need to isolate the circuit you are measuring from anything else that would impact the reading. In the case of a temp SENSOR ( temperature sensitive switch) it is either open or closed. But to prove that you disconnect the lead at the sender. Now ...

Testing the Jaguar Coolant Temperature Sensor

Compare with the log provided above, for correct ohm readings at the current engine temp. The ohm reading should be very close to to the ohm readings when just testing the CTS by itself. Have an asst shake/wiggle the CTS wire harness, and observe the meter. If the ohms vary from the ohm reading on the CTS, the harness is faulty, or the connector is corroded. Clean the contacts and recheck. If ...

420A - Coolant Temperature Sender Values? |

2021-07-28· The resistance was way off per the values in the Manual for that temperature. I'll see if I can upload the values from my Haynes Manual had for various temperatures. The ECU uses coolant temperature as one of the inputs for determining proper Fuel delivery and Air/Fuel ratios. FYI I have a 420A (1995 Talon). I purchased a new sensor on Rock Auto for replacement. I hope this helps.
