Coolant temperature sender
Posted 14 July 2004 - 05:24 PM
I'd like to investigate the connections at the coolant temp sensor for corrosion hoping I can just clean it up and get the guage working again. This is probably obvious to most but I'm new to auto mechanics and have questions.
Does this engine EA82 (non-turbo) have more than one sensor or just the single one on the thermostat housing?
Assuming that's the one that sends a signal to the dashboard guage, theres a short (~ 2 in) wire coming out of the sender that ends in a green plastic connector. I pulled the connector apart and it looks clean in there. So to check the connection at the sensor do I just yank the wire off at t-stat housing? I tugged a little and it wasn't coming off easily so I stopped.
I'd appreciate any input.

At 122 deg. F the sensor resistance should be around 154 ohms.
At 248 deg. F the sensor resistance should be around 16 ohms.
I would guess that at normal running temps the resistance would be about 40 to 50 ohms.
If your first post stated the resistance is only 2 ohms then this really is bad but you need to remove the sensor lead before taking a reading so the reading is accurate.
