ticking sounds from the engine

was the CEL on? was it on before the ticking started? when did it start ticking? all the time? engine cold/warm?

p0130: O2 sensor code
p1290: Engine Coolant Temperature code
p0171: Fuel Trim code

These codes "might" not be related to the ticking.

Most common ticking sounds are:

- hydraulic lifters - due to low oil pressure
- chain tensioner (1.8T) - worn out or due to low oil pressure
- VR6 chain rattle - broken chain guides

You need to have a professional listen to your engine to make sure
that it is not something serious.

You can deal with the codes at a later time.
