head temp sensor
 

I know there is a test for this with an ohm meter but I'm not sure what the reading should be. Is there a range for hot and one for cold. I did a search and found a few posts on the test but nothing about what the proper resistance should be.

Is there a similar test for the idle stabilizer valve?

and while were here how about the O2 sensor?

Typical temp sensors have the following values;

Cold 2.5K ohms to 3.3K ohms, hot - 250 to 375 ohms

Idle stabilizer valves (3.2) 22 ohms between center and each outside pin.
As for the 3.6 (It's not push-pull but single-ended single drive. ), it's about
15 to 30 ohms between pins.

The O2 has infinite resistance when cold. When hot, you check its voltage,
lean < .50 volts, rich > .50 volts

Thanks Loren,

between the two pins my temp sensor reads 18 ohms when cold and 15 ohms when the engine is 180 degrees.

between the two pins my idle stabilizer valve reads 8 ohms when cold and 6 ohms whith the engine at 180 degrees.

didn't measure the O2 sensor, car idles better with it plugged in but seems to hesitate at higher RPM's when accelerating. With the O2 unplugged the car accelerates great but has a rougher idle and occasionally really stumbles when decelerating.

I think I'll order a new 02 sensor but can comeone confirm the head temp sensor values?

The numbers are not correct. Check the scale on your meter. Use a known
value of a resistance (100 ohms from Radio Shack) to check the meter.
The 964 DME goes to default values when sensors are not plugged-in.
The AFM may be sticking or not adjusted correctly causing a flat spot
during accel.

Scale on my meter was x1, just checked a new beru connector I had left from my 3.0L, distributor cap side, 1,000 ohms. I'll run out later and get a resistor to double check.

Is it possible the 3.6L temp sensors are different than the 3.2L's? Seems like they would be the same.

They're basically the same values.
