Replaced the coolant reservoir, and the light still won't turn off. I recently replaced the block heater as well. Also had the fuel injectors were replaced due to 3 of them cracking and forcing all the oil out of the engine and replacing it with diesel. Truck runs fine, and there are no leaks other than a small power steering leak.

Hi,

There is a chance we lost ground or sensor is faulty. Did you also replace the sensor?

Interestingly, I found a technical service bulletin (TSB) related to this issue, so it must be a common problem.

If you look below, I attached the diagnostics from the TSB. Take a look through them and let me know if you are comfortable performing them.

Take care,

Joe
