What is the code P0016 on a Ford f150?

P0016 on a Ford F-150 is a Crankshaft Position-Camshaft Position correlation fault, most often tied to Bank 1 Sensor A. In simple terms, it means the engine computer is seeing a mismatch between the crankshaft and camshaft position signals, which can affect timing and engine performance.

This article explains what the code means for Ford F-150 owners, common causes, and how to diagnose and address the issue safely.

What P0016 Means for the Ford F-150

P0016 is an OBD-II code indicating a timing correlation problem between the crankshaft position sensor (CKP) and the camshaft position sensor (CMP). The engine control module (ECM/PCM) relies on synchronized CKP and CMP data to time fuel injection and spark. When the signals don’t correlate within expected parameters, the PCM sets P0016 to prevent potential engine damage from incorrect timing. On most Ford F-150 engines, this is recorded as Bank 1 Sensor A (the primary cam/crank timing reference for the engine).

Common Causes

Below are the typical reasons a Ford F-150 might register P0016. Inspect each area, starting with the most common or easiest to access.

• Timing chain/belt wear, stretched timing chain, or jumped timing resulting in misalignment between CKP and CMP signals.


• Faulty crankshaft position sensor (CKP) or camshaft position sensor (CMP).


• Wiring harness damage, corroded connectors, or poor electrical connections to CKP/CMP sensors.


• Oil contamination or insufficient oil pressure affecting cam phaser or sensor operation.


• Problems with variable valve timing (VVT) solenoids or cam phasers causing improper phasing.


• Timing components such as tensioners or guides wear or failure.

Note: Some Ford engines and model years may also register P0016 due to calibration or software issues, or an aftermarket tune affecting timing reference data. Always check for engine-specific service information for your exact year and engine family.

How to Diagnose and Fix

To approach a P0016 diagnosis, follow a structured process that prioritizes safety and accuracy. The steps below provide a practical path for many Ford F-150 engines, but refer to your service manual for exact specifications.

1. Confirm the DTC with a scan tool and review freeze-frame data for sensor readings at the time of failure.


2. Inspect CKP and CMP sensor connectors for looseness, corrosion, or damaged wires; reseat or replace as needed.


3. Check timing alignment using the manufacturer’s procedure for your engine. If equipped with a timing chain, verify chain alignment marks and ensure the chain hasn’t jumped one or more teeth; for belt-driven engines, inspect belt alignment and condition.


4. If timing appears off, inspect timing components: chain/belt, guides, tensioners, and cam phasers. Look for signs of wear, noise, or oil pressure issues.


5. Test or replace CKP/CMP sensors if electrical checks indicate faults, using proper torque and gaskets.


6. Check engine oil level and quality; replace oil and any contaminated filters if sludge or oil degradation is suspected, since oil can affect timing components in some engines.


7. Clear codes and perform a road test to verify if P0016 returns. If the code reappears, seek professional inspection, as severe mistiming can cause engine damage if driven for extended periods.

Because timing-related problems can lead to serious engine damage, avoid forcing the engine to run aggressively if you suspect the timing is off. If in doubt, have the vehicle inspected by a qualified technician.

Summary

P0016 on a Ford F-150 signals a Crankshaft Position-Camshaft Position correlation fault, typically Bank 1 Sensor A. It points to timing or sensor/wiring issues rather than a single, simple sensor fault. Diagnosis involves verifying timing alignment, inspecting CKP/CMP sensors and wiring, assessing timing chain/belt and related components, and replacing faulty parts as needed. Addressing the issue promptly helps prevent potential engine damage and costly repairs.

For model-year-specific guidance, consult Ford’s official service information or a qualified technician who can tailor the diagnosis to your F-150’s exact engine and configuration.

How much does it cost to fix the P0016 code on a Ford?

Replacing the cam and crank sensors is one of the most common repairs for the P0016 code. Replacing a cam and crank sensor usually costs about $200 with labor. If you are going to do the replacement yourself, the price range for the sensor is about $15-$150.

Repair Solutions
You may need to replace or realign your timing belt or chain. Your tensioner may also be damaged, causing your belt to become misaligned. Use a scope to check the camshaft and crankshaft patterns. Inspect the crankshaft harmonic balancer and tone rings for any visible damage or misalignment.

Is it safe to drive with a P0016 code?

No, you should not drive with a P0016 code because it indicates a serious engine timing issue that can cause severe engine damage, poor performance, and potential stalling. The code means the crankshaft and camshaft positions are not synchronized, which can lead to misfires, rough idling, difficulty starting, and, in the worst case, complete engine failure if ignored.

Risks of driving with a P0016 code

• Severe engine damage: The timing misalignment can lead to internal engine damage over time. 
• Stalling and rough running: You may experience stalling, a rough idle, or hesitation during acceleration, making the vehicle unsafe. 
• Poor performance: Expect reduced power, poor fuel economy, and a significant decrease in overall engine performance. 
• Escalating costs: A small issue can worsen over time, potentially leading to a more expensive repair, such as a full timing chain failure. 
• Limp mode: Some vehicles may enter "limp mode," which limits engine power to prevent further damage. While this helps, you should still not rely on it for daily driving.

What you should do

• Stop driving: It is best to stop driving the vehicle as soon as you notice the code. 
• Diagnose the problem: Use a scan tool to confirm the code is active. If it reappears immediately after clearing it, the issue is ongoing and needs professional attention. 
• Get it repaired: Have the vehicle towed to a qualified mechanic for a proper diagnosis and repair. 

What is the most common cause of P0016?

As that may allow the timing of the crankshaft. And cam shaft to come out of sync.
