P0016 Saturn Code - Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor 'A'

Quick Answer

The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. Common causes include Mechanical timing fault (stretched timing chain or damage timing chain tensioner), Blocked oil passage, Low oil level. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0016 Saturn Description

The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. The magnetic field of the sensor is altered by a crankshaft mounted reluctor wheel that has seven machined slots, 6 of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees after one of the 60 degree slots. The CKP sensor produces seven pulses for each revolution of the crankshaft. The pulse from the 10 degree slot is known as the sync pulse. The sync pulse is used to synchronize the coil firing sequence with the crankshaft position. The CKP sensor is connected to the Powertrain Control Module (PCM) by a signal circuit and a low reference circuit.
The Camshaft Position (CMP) sensor is triggered by a notched reluctor wheel built into the exhaust camshaft sprocket. The CMP sensor provides 6 signal pulses every camshaft revolution. Each notch, or feature of the reluctor wheel is of a different size for individual cylinder identification. This means the CMP and crankshaft position (CKP) signals are pulse width encoded to enable the PCM to constantly monitor their relationship. This relationship is used to determine camshaft actuator position and control its phasing at the correct value. The PCM also uses this signal to identify the compression stroke of each cylinder, and for sequential fuel injection. The CMP sensor is connected to the PCM by a 12-volt, low reference, and signal circuit.

Code Tech Notes

If this Diagnostic Trouble Code (DTC) started after recent internal engine repairs, inspect for proper engine mechanical timing. With the camshaft cover removed and the #1 cylinder at top dead center, make sure that the darkened chain links are lined up with the alignment marks on the exhaust and intake cam sprockets.

If a P0016 is resetting without any engine performance concerns but the above information did not isolate a cause for the DTC, replace the Cam Phaser Actuator sprocket.

There is a factory service bulletin for the following Saturn models:
2007-2009 Saturn AURA
2008-2010 Saturn OUTLOOK
2008-2010 Saturn VUE
Saturn Factory Service Bulletin OBDII Code P0016

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0016 Saturn code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
