AKA looks like my dash gauge might also be shy by about 5 C. At 100C, the sensor read about 800-900 ohms. I was thinking the range should be 500-600 ohms-but don't know without checking a bosch book.

I'm headed for emission testing soon too. My plan of attack is new plugs, oil change, and O2 sensor. It did not start today instantly at 75 F, so I'm guessing my mixture is off a bit.

Though it may not seem so I do have the manual. The emissions world has been to me like aincent greek but I have learned a lot in the last 72 hours.

I found the water temp sensor Ohm's range at the temp chart in the /Engine Manual-Combustion Manual-07.3 Mechanical/electronic gasoline injection system (KE injection)-121 Testing electrical components of KE injection system. page 60

Temperature C........Resistance kΩ
-20........................15.7
-10.........................9.2
0............................5.9
10...........................3.7
20...........................2.5
30...........................1.7
40...........................1.18
50...........................0.84
60...........................0.60
70...........................0.435
80...........................0.325
90...........................0.247
Same resistance values apply to KE intake air temp sensor.
I think this chart applies to these 2 sensors for all KE systems but don't know for sure.

My water temp sensor is not in line with these values.
I may also have a bad o2 sensor (wish I had a scope to get a clear view)
Now I am waiting for my water temp sensor to arrive.

75F ay...must be nice.

P.S. anyone know if there is a better tool than a 22mm crows foot to get these sensors off and on again?
