Coolant sensor was replaced still get check engine light

I took my navigator to advance auto to diagnose a check engine light problem. It said the coolant sensor needed replacing. I replaced it and that seemed to correct the fault. About two days later the check engine light came back on. I took it back to advance auto and the computer gave the same fault....help, Rickey

If the code in the ecm isn't cleared then it will come back. Have them clear all codes and see if it persists.

2004 Lincoln navigator engine light stays on


If you have a simple scanner, you can diagnose this right away. If not, your 'nice guy' auto parts store can diagnose for you for free, just buy the part from him. You most likely have a sensor problem.

The engine light came on took it to auto zone had it diagnosed, said to either change the thermastat or coolant sensor, did both, engine light stayed off for one week now its back on


Check the coolant sensor plug to make sure its connected securely. If that doesn't fix it then take it back and have them recheck the code. Hope this helps!

Most check engine lights will come on due to and emission problem. Stop by Advance Auto Parts and let them read the codes. It is probably a sensor.

2004 Kia Sedona, Engine light comes on and off, usually comes on when it is wet outside, like after a good rain and is now on because of winter.


Could be one of many...mechanic would be better at diagnosing. Things to try...coolant temp sensor, distributor cap, spark plugs and wires. Coolant temp sensor would be my first guess. Would recommend taking it to a mechanic or Advanced Auto Parts (they check codes for free) while the light is on. They can hook up their computer and find out what codes are being thrown up and better give you an idea on what to fix.

Check engine light - P0420 code


Causes A code P0420 may mean that one or more of the following has happened:
  • Leaded fuel was used where unleaded was called for
  • An oxygen sensor is not reading (functioning) properly
  • The engine coolant temperature sensor is not working properly
  • Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
  • Retarded spark timing
  • The oxygen sensors in front and behind the converter are reporting too similar of readings

Coolant Temp Sensor


The sensor is located on the drivers side engine block...although you can see if from looking from the top of the engine, you would have to get under the vehicle and look up to replace it. Be aware that it takes a special tool to unscrew the old one and screw in the replacement.
