Hi,

My temp gauge reads very low.

on by CIS car, a temperature sensor for the coolant sits in the thermostat housing.

1. Is this for the gauge only, or does it affect HVAC, fuel-injection or other systems?

2. From the WSM:
"Temperature sender, cooling water
A resistance of between 1000 ohm
and 4000 ohm, depending on
engine temperature, should be
measurable between pin 1 of plug
II and pin 7 of plug I.Reading:

60°C = 3862 ohm +/- 150 ohm
85°C = 1582 ohm +/- 54 ohm
100'C = 967 ohm +/- 36 ohm"

Problem is: the wsm refers to pins on a control unit that my old car does not have. But the sensor is the same (verified in PET).

With my multimeter I am not able to measure any resistance (well actually infinite) between the connectors on the sensor itself (as shown in the picture).

I would like to verify that the sensor is OK, and what temperature my car operates at. I was planning fo verify the sensor first, but how?

Any input apprechiated.
