THOMAZ31

Dear Friends,
The CEL came on a few days ago and I stopped using my 2005 A4 2.0. Temperatures fell to -20 here in Vermont so I let the car sit for a while, refusing to drive it. Today, 40º temperatures, I went 1/4 mile to our local O'Reilly's and discovered the P 0340 error from the CEL.

After doing simple searches it's clear that I can change this and do whenever possible to defray costs. Is there anything else I should watch out for? Also, is there a specific part that I should use over others? O'Reilly's has one - it's inline - (Import Direct 3 Terminal Engine Camshaft Position Sensor) I want to be sure before I make the move.

The car is not running particularly rough, although within a few days of the CEL appearing the car did stall once.

Thank you all so much - any advice will be greatly appreciated. Thomas

I would try disconnecting and then reconnecting the sensor's harness connector first. Use an electrical contact cleaner spray on the contacts and allow to dry before coupling back together. If that doesn't fix it, then try changing the sensor. Keep in mind that even a new sensor may not be the solution if there is a wiring break or poor connection somewhere else in the circuit. You might want to search some common online parts sources such as ECS Tuning, FCP Euro, autohausaz, etc to compare brands and prices.
