Fault code P0016 on a Hummer indicates a misalignment between the camshaft and crankshaft position sensors.

P0016 can be caused by a mechanical timing fault (stretched timing chain or damaged timing chain tensioner).
A blocked oil passage.
Low oil level.
A faulty Intake (‘A’) Camshaft Position (CMP) Sensor.
A faulty Crankshaft Position (CKP) Sensor.

Fixing Hummer Error Code p0016 Step By Step

Addressing Hummer P0016 involves inspecting the camshaft position sensor and crankshaft position sensor for proper operation.

To fix P0016 OBDII code, review the possible causes related to the crankshaft position sensor and camshaft position sensor.
Visually inspect the wiring harness and connectors for any damage.
Check the connector pins for signs of being broken, bent, pushed out, or corroded.
Test the crankshaft position sensor and camshaft position sensor for proper operation.
Replace any faulty sensors if necessary.
Clear the fault codes and perform a test drive to ensure the issue is resolved.

Cost Of Fixing Hummer p0016 Fault Code

The repair for Hummer P0016 may involve replacing the camshaft position sensor or adjusting the timing chain.

The cost to diagnose and fix a Hummer OBD code P0016 typically ranges from $75 to $150 per hour for labor rates.

With an estimated repair time of 1. 0 hour, the total cost can be around $75 to $150, depending on shop rates and the complexity of the repair.

Details of the Hummer p0016 OBD Code

Fault code P0016 in a Hummer indicates a crankshaft positioncamshaft position correlation error.

OBD code P0016 for a Hummer indicates that a camshaft position sensor correlation problem has been detected between the camshaft position sensor and the crankshaft position sensor.

This code is triggered by the Engine Control Module (ECM) when it detects that the camshaft and crankshaft are out of sync.

In this case, the component that triggers the code is the camshaft position sensor and the crankshaft position sensor.

These sensors provide crucial data to the ECM for proper engine operation and timing.

The signal or system involved in this fault code is the synchronization between the camshaft and crankshaft positions.

When these two components are not in proper alignment, it can lead to issues with engine performance, fuel efficiency, and emissions.

Mechanic’s Tech Notes

Detailed information on diagnosing and repairing Hummer P0016 code related to camshaft position sensor correlation issues.

To diagnose and fix OBDII code P0016 on a Hummer, start by checking the camshaft position sensor and crankshaft position sensor signals using a voltmeter.

Ensure the signals are within specifications.

Next, inspect the timing chain alignment and tension.

Use a scan tool to monitor camshaft and crankshaft correlation while the engine is running.

If the correlation is off, the timing chain may need replacement.

Additionally, check for any oil sludge buildup that could affect sensor readings.

Finally, inspect the wiring harness and connectors for any damage or corrosion.

Repair or replace components as needed.
