It is most likely the TPS sensor for the P0123 code(TPS voltage out of range). If P0123 occurs again, repair. The P0162 may be a result of the P0123 failure. So repairing the P0123 may also correct the P0162 fault.


The P0162 appears to be Jeep enginr specific. The following link may be of help.

2004 Jeep Grand Cherokee temp gauge high when heat is on


If your "check engine" light is turn on, I suggest scanned the PCM to know exactly what fault code is stored there. Additionally, could be some problem with the "temp sending unit".

Keep us updated.

What causes the oil pressure gauge to fluctuate on my 2004 Jeep Grand Cherokee Laredo?


If the oil pressure is good and there is no engine noises then the oil pressure sending unit is the problem.Just replace it and you should be good.Hope this helps.Good luck.

most of the time it means you should get your oil changed,and if you look in your owners manual it will tell you by mileage other items that should be taken care of when the light comes on.

Oil light flashing, last oil change 7 wks ago


I belive they didn't reset the oil light timer. I belive the sequence is 1. key on (not acc with engine off)
2. step on the brake pedal 5 times within 10 seconds. 3. key off. 4. start car. 5. check if the light went out. you may have to try it a few times to get it.
