What Does Chevrolet Silverado 2500 HD Code P0014 Mean?

- Issue Severity: SEVERE – Stop driving immediately.
- Repair Urgency: Fix this code immediately (same-day if possible) to avoid damage to multiple internal engine components.
- Diagnosis: This trouble code severely impacts the drivability of your vehicle. The most common problems consist of increased engine stalling, rough engine idle, lowered fuel economy, and rattling/knocking noises from the engine.
The variable valve timing system increases fuel economy and engine performance by regulating when the intake and exhaust valves are opened and closed. The camshaft(s) is(are) adjusted by the engine computer through the use of an oil control valve(s) (OCV), also called variable valve timing control solenoid valves. When trouble code P0014 is set, it means that the exhaust camshaft in Bank 1 is more advanced than the engine computer has told it to be.

DIY Steps to Diagnose Chevrolet Silverado 2500 HD Code P0014
Engine code P0014 could be caused by a number of things, including old oil, the camshaft variable timing solenoid, the camshaft phaser, and more. If you’d like to try to fix code P0014 at home without throwing money at parts, you’ll want to follow the steps below for proper diagnosis. Keep in mind this is an intermediate-level diagnosis and repair and not recommended for beginners. Diagnosis beyond oil level and condition requires more specialized equipment beyond what the FIXD Sensor can provide and it can be a time and labor-intensive process for inexperienced DIYers.

STEP 1: USE FIXD TO ENSURE NO OTHER ENGINE CODES ARE PRESENT.
Use FIXD to scan your vehicle to verify P0014 is the only code present. If other codes are present, they must be addressed first.
STEP 2: CHECK THE OIL LEVEL AND CONDITION.
If the oil level is low, adjust to spec and test drive to see if the concern is resolved. If it’s dirty, change the oil and filter and test drive to see if the concern is resolved.
STEP 3: INSPECT THE VALVE TRAIN FOR SLUDGE.
Remove the oil cap and/or the valve cover and inspect the valve train for sludge. If there is sludge, there is a good chance the engine will need to be replaced due to sludge blocking the oil passages to the Oil Control Valve(s).
STEP 4: CHECK VALVE FOR PROPER FUNCTION.
If there isn’t any sludge, consider checking the Bank 1 Exhaust Camshaft Oil Control Valve for proper function. You can do this by removing the Oil Control valve and supplying power and ground to the solenoid quickly using a pair of fused jumper wires. (Do not leave power applied for more than a second or two) If the valve is functioning properly, it should click, and you may even be able to see the valve move based on the design of your specific valve. If it doesn’t click or move, replace the tested oil control valve and test drive to see if the concern is resolved.
If at this point the concern persists, there could be internal engine issues, and you should have a shop diagnose the concern to avoid replacing the engine unnecessarily.
