17748/P1340/004928 - Camshaft Position Sensor (G40) / Engine Speed Sensor (G28): Incor. Correlation
Possible Causes
Timing Belt/Chain incorrectly installed
Timing Chain probably lengthened
Camshaft Position Sensor (G40) faulty
Engine Speed Sensor (G28) faulty
Possible Solutions
Check Timing Belt/Chain installation
Use Measuring Value Blocks (MVB) to Check Timing Chain
Check/Replace Camshaft Position Sensor (G40)
Check/Replace Engine Speed Sensor (G28)
Special Notes
When found in the 1.8T engine, check engine oil pressure. The oil pump pickup may be restricted.
When found in the 1.8T engine (possibly others too), check to make sure the correct G40 is installed (single gap versus 4 gap).
When found in VR6 4 Valve (BDF, BJS, BAA,) engines in conjunction with 17755 please see Technical Bulletin 15-07-03. The previous Technical Bulletin number was 15-04-01.
When found in a 30-valve V6 gasoline Audi engine (such as EPB or BEL), DTC 17755 may be stored as well. If both of these codes are displayed simultaneously, and the codes only appear after the motor is revved above 1800RPM, then the issue is likely that the cam chain tensioners were installed on the incorrect heads (drivers' tensioner on passenger head, etc).
tylko chech sie pali, czy EPC też? jakieś niepokojące objawy, których nie było wcześniej?
