Temp guage sensor pn 035 919 369 L
FYI, I think I've finally got a handle on this one. AudiOnly gave me the
part # and cost of 44.00 plus shipping which is probably hard to beat. Since
this is Temp sensor # 2 acting up (junkyard part) I'll probably order it soon
(and take one of the old ones apart to see what is what - probably an RTD w/
linear OpAmp). This sensor provides input to the OXS unit (pin 2/B, current
track 129 to 41/42), the AutoCheck unit (pin 4/C, current track 130 with
coolant low level sw), and the Temp guage (pin 1/A, current track 130 to
260). Power comes into current track 128 from 203 via fuse S12 (15 amp).
It appears to be an intermittent open - not necessarily temperature
dependent. I can tap lightly on mine with a wood handle screwdriver when
it's acting up w/o touching anything else and 90% of the time it will work
fine after that.
This switch is also on other models besides the 87/88 5KCSTQ. The Bentley
TS&R section only covers the earlier two wire sensor (simple RTD). The
important part to remember is that this may fuss up your FI too. Throws mine
for a loop! I had thrown out the idea of the voltage stabilizer being bad
early on, since only the temp guage was acting up.
Replacement is a simple 5 minute job with a metric adjustable (8" or 10") and
a quart loss of coolant. Not a bright idea to try to replace hot.
Especially easy if you remove the upper tri-y radiator hose first. Unplug,
Hope this helps! Thanks to everyone for their input. I'm going to put
together a package on all sensors one of these days, submit it to the group
for edit, and then send it to the archives.
