My temp gauge goes to H (overheat) somewhat erratically and I do not suspect any real overheating problem. I've heard of this as a common 3rd gen Maxima problem.

Anyone know if this is a common problem? Fix??

Thanks,

Need a little help. Anyone????

 

could be the gauge itself or the ECTS is bad

 

I just changed the gauge cluster, and is exhibiting the same behavior so I don't think its the gauge. Also, at time it moves irratically up and down - suspect some kind of sensor?

 

Close but not quite. . the ECTS supplies temp readings to the ECU.. the sensor right next to it is the sensor for the temperature gauge

 

My gauge was doing that, so replaced the sensors & it didn't help. It turned out that it was actually overheating, but it didn't feel like it under the hood.

My problem was caused by a wornout water pump seal, it was causeing an air bubble, and as the bubble moved it cause the temp to move up & down.

$598 later I had a new water pump and the problem was solved.

 

Thanks,

I'll get it checked

I figured that since goes up and down quickly that it couldn't be real - but better safe than toast.
