Coolant Temperature Replacement

Recently began getting a bothersome CEL (check engine light) illuminated and throwing a P0115 code.

Image


I cleared the code several times but it always came back on. I finally relented and purchased a new sensor Part # 0005425118 from Auto Parts at AutohausAZ - OEM Auto Parts - Discount Replacement Parts, Resources and Car Care Tips at a cost of $10.50.

I waited for a mild day weather wise and today was it so I proceeded.

Location of the sensor is on the front of the motor under the front cover.

The sensor is only held in by a simple horse shoe clip which must be pried out to release the sensor. The horseshoe clip applies pressure to the sensor collar which forces the o-ring on the stem to seal. Unplug the connector by pressing in on the tab (one side only)to release the lock,(of course my tab broke off!) remove the connector and then pry out the horse shoe clip and remove the sensor.

Out comes the clip, (reverse for re installation of new sensor).

New sensor with horse shoe clip.

Old Sensor compared to new.

And finally, clear code and hope code does not reappear.

Finally, this is a very easy repair. There will be little to very little coolant loss so no need to do any draining of system. I just put a piece of cloth under the hole to absorb the very little drainage.

Start motor and let warm up to check for leaks. So far so good!! :thumbsup:

ibeforreal, Yes putting the clip back in can be a problem, but when you have more room, especially right above it, it makes all the difference. Its just the smog pump, the black box, and comes out, at least on mine, 2002 s500, with the removal of the top bolt, 10 mm, and the front plate comes off, and the whole pump comes sliding out, thus giving plenty of room from the top to put the clip back in with no problem at all. Hope that helps.
