I have a 2006 cadillac sts V6 and have the P0008 code. Is it easily fixable or do I need 13 hours of labor?

Your model has variable valve timing. I'm guessing he intends to replace the whole timing set. He will not be able to decide what is wrong without taking off the timing chain cover and both valve covers. He is probably quoting the hours for that task from industry tables, but there is no harm in getting a second opinion. Are you noticing any symptoms aside from the engine light? If performance is affected, I would do as I have noted above. Also make sure you are getting regular oil changes, as sludge can cause this fault.

DTC P0008 Engine Position System Performance Bank 1
The engine control module (ECM) tests for a misalignment between both camshafts on one bank of the engine and the crankshaft. The misalignment would be at an idler sprocket for bank 1 or at the crankshaft. Once the ECM learns the position of both camshafts on one bank of the engine, the ECM compares the learned values to a reference value. If the ECM detects both learned values for one bank of the engine is exceeding a calibrated threshold in the same direction, this DTC sets.

Diagnostic Aids
• Inspect the engine for any recent engine mechanical repairs. An incorrectly installed secondary timing chain can cause this DTC to set.
• A single failed camshaft actuator or actuator solenoid will not cause this DTC to set. This diagnostic algorithm is designed to detect an alignment condition between a primary intermediate sprocket and the secondary timing chain, or the alignment between a primary intermediate sprocket and the crankshaft. Either condition would cause the camshaft timing for both cams on one bank to be off an equal number of degrees.
• The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no longer referenced to top dead center (TDC).
• Observing the desired and actual camshaft angle parameters, with a scan tool before a DTC sets, may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.
• For an intermittent condition, refer to Intermittent Conditions .


How many mile on the vehicle ? Maybe time for new timing components - chains - gears etc....
