2013 Ram 1500 Check Engine Light - Coolant Sensor

[Mike_P]

Check engine light on apparently due to engine coolant sensor per Autozone. Replaced sensor and 2 days later check engine light on again. Same error code. Anyone have an idea what may be the issue?

Short in wiring to sensor?

Aftermarket or OEM ?
I have found that these trucks (engines) do not like aftermarket!

It is likely the float inside the coolant bottle that has gone bad. I know on the 2500's it is a common problem. You have to change the coolant bottle for a new one. This video will show you how to check the sensor: https://youtu.be/gB0-2aMFcZ0?si=02LREd_sGyeaDW4n But more than likely you'll need tot replace the coolant bottle.

Always use OEM sensors , unless you enjoy rerepairing issues.
