Hello Folks...
Audi A4 1.6 2002 check engine light came on. Got the car scanned. Code scanned is P1290 coolant temperature sensor output too high.
I got a temperature sensor replaced 6 months ago. The green one behind the engine passenger side.
Question...

How many temperature sensor does the above model have?

Could the problem be the same CTS I happen to have replaced 6 months ago?
Your help will be appreciated. Thank you
