CTS Sensor LET?

hi,

Does anyone know if the CTS sensor can be faulty but not show a high/low voltage on the ECU fault codes?

Regards

CTS Sensor does degrade in signal response with time, a failing CTS does not always raise a fault code it just provides the ECU with an incorrect coolant temperature. Will eventually supply a bad reading out of ECU tolerance (which is when a code is raised). Symptoms can include poor start, rough idle and rich running/poor petrol economy.

Cheers lads!

Seems to run bad when hot. Everything else (mechanical) is ok. No ECU code but its like a rocket when cool which makes me think CTS is out.

Will change tomorrow and update the thread.
