Coolant sensor G62

Recommended Posts

Finally got this fault to show up consistently (30-00 Open or Short to Plus) - symptoms are exactly per Ross-Tech's website (occasional loss of power 'hiccups' when at part-throttle, occasional difficulty starting from cold, poor mpg, poor acceleration when cold etc). Previously when I've reset it it hasn't come back for a while - this time resetting it caused the idle to instantly rise ~100rpm before the fault code came back and the idle dropped again. This makes sense as a detected fault causes the ECU to use the default value of 80ºC, so it's using the default value and then tripping again.

 

Am I right in saying that this is the two-pin blue sensor in the thermostat housing? Will have to have a look at the wiring harness, I think...
