OBD-II Code P2614 — What It Means & How to Fix It

What it means

P2614 indicates a fault in the camshaft position signal output circuit — the ECM is not correctly processing or transmitting the cam signal to other modules.
The ECM uses the cam signal to time fuel injection and spark precisely.
Symptoms include rough running, stalling, no-start, or erratic engine behavior.

Affected Models

All vehicles 1996+
Common in GM vehicles with overhead cam engines
Common in Ford vehicles with variable valve timing
Common in high-mileage vehicles with stretched timing chains

Common Causes

Failed camshaft position sensor no longer sending a signal
Damaged reluctor wheel on the camshaft disrupting the signal pattern
Wiring fault between the ECM and downstream modules receiving the cam signal
ECM fault — the module is not correctly processing or transmitting the cam signal
Timing chain stretch causing incorrect cam signal timing relative to crank position

How to Fix It

Check for companion codes — cam and crank correlation codes help narrow diagnosis.

Codes like P0016 (cam/crank correlation) or P0340 (cam sensor circuit) alongside P2614 point to the specific failure area.
Inspect the camshaft position sensor connector and wiring for damage.

The sensor wiring runs through the engine bay and can be damaged by heat, oil, or accidental contact during other repairs.
Test cam sensor output with a scanner in live data mode — watch signal pattern.

A working cam sensor produces a clean square wave pattern.
A missing, erratic, or flat signal confirms the sensor or circuit has failed.
Check timing chain condition if other codes suggest cam/crank correlation issues.

A stretched timing chain causes the cam signal to arrive late relative to the crank signal — this looks like a sensor problem but requires a timing repair.
Replace the cam position sensor if it fails output testing.

Cam sensors are usually inexpensive — replace the sensor first unless timing chain wear is confirmed by other diagnostics.

When to Call a Professional

A missing cam position signal can cause sudden stalling — do not drive the vehicle if it is running poorly.
A technician will check for companion codes, inspect the sensor, and test cam signal output with a scan tool.
Cam sensor replacement is typically $100–$250; timing chain issues can run $600–$2,000+.

Frequently Asked Questions

Can I drive with P2614?

Not safely.
A missing cam position signal can cause sudden stalling with no warning.
The engine may also refuse to restart after stalling.
Get it towed to a shop if the car is not idling reliably.

How often should cam sensors be replaced?

There is no fixed replacement interval — cam sensors usually fail without warning.
Most last well over 100,000 miles before failing.
Replace them when they show signs of failure rather than as preventive maintenance.

How much does a cam sensor cost?

Usually $15–$80 for the part itself.
Labor is typically 30–60 minutes depending on sensor location.
Some vehicles have multiple cam sensors — all should be tested when one fails.
