Coolant Sensor

[Sinbad the Sailor]

On my way home from getting my car fixed (yay!!!:)) I was datalogging and I noticed that my CLT was way off and causing warmup enrichment during normal driving. So I had to turn off the warmup enrichment as it was running way rich but that is just a temporary fix.

I have this CLT

Bosch Sensor- Part #0 280 130 037
Thread Size 14mm X 1.5 pitch
Resistance: Approximately 200 ohms at 212 degrees F (100C), approximately 2800 ohms at 68F (20C), and approximately 6000 ohms at 32F (0C), and approximately 11,000 ohms at-4 degrees F, (-20C).

My question is could my CLT be fubared? It has always been jumpy but now it's really bad and way off the correct temp. I also noticed that it would jump when I pressed on the gas. It was immeadiate so I know that the coolant couldn't heat up that fast. So that leads me to believe it is just a bad ground connected to the tps ground.

What do you guys think?

Did you check your CLT sensor settings?

Did you check the Ohms readings of the sensor?

Did you check to see if the plug is secure on the CLT sensor?

I have been using the same CLT sensor for the past 3 years without a problem. Checking the ohms of the sensor should be able to tell if you have a bad sensor or not.
