      2009: No Tachometer Reading

      2009 Aveo5. Suddenly the tach is not reading at all. No codes are being set. A scangauge is attached in the car at all times, but it shows no RPM reading on it, either. The car seems to run fine with no performance issues at all. WTF?

      Any ideas?

      What do you mean there's no turbo?

      According to the service manual, the crankshaft position sensor is what sends the tach signal.

      Located on left rear of engine, below oil filter (per the manual).

      At $30 on amazon (part 55555806), it might be worth it just to throw the part at it first before any other troubleshooting.

      As of today the tach is back to acting normally, which adds to the frustration of having an intermittent and unresolved problem, and being clueless about it. Initially I thought that it might be a sensor that is failing, because it affected nothing else. If this continues to act up I'll buy the part and install it before doing anything else. Let's hope that it's only that.

      All my other cars are much older than the Aveo, so I'm not used to troubleshooting and dealing with the imposition of BS sensors that regulate every minute detail of a car. IMO, on most modern machines and appliances it's the electronic parts that are the first to fail.

      Many thanks for your help!
