Check These First (Before Buying Parts)
- Visually inspect the wiring and connectors for the crankshaft and camshaft position sensors for any signs of damage, corrosion, or looseness.
- Ensure the sensors are securely mounted and free of debris.
How to Diagnose P0375
- 1Visually inspect the crankshaft and camshaft position sensors and their wiring for damage or loose connections.
- 2Check for other related trouble codes, especially P0335, P0336, P0340, P0341, which can point to specific sensor issues.
- 3Use a multimeter to test the resistance of the CKP and CMP sensors, comparing readings to manufacturer specifications.
- 4Use a scan tool with live data to monitor the CKP and CMP sensor signals while cranking or running the engine.
- 5If sensors and wiring check out, inspect the tone rings for damage or debris.

Frequently Asked Questions
What does P0375 mean?
P0375 indicates that your engine's computer is not receiving a precise, high-resolution signal from a sensor that tracks the engine's position. This signal is crucial for the computer to accurately time spark and fuel delivery.
Can I drive with P0375?
Limit driving, fix within a few days. This code points to a critical engine timing issue. Driving with P0375 can lead to stalling, misfires, and potential engine damage if ignored.
Will P0375 clear itself?
No, P0375 will not clear itself. This code indicates a hard fault with a critical sensor or its circuit. The underlying problem must be diagnosed and repaired before the code will clear, either automatically after several drive cycles or by using a scan tool.
How do I fix P0375 myself?
Start by visually inspecting the crankshaft and camshaft position sensors and their wiring for any obvious damage or loose connections. If no issues are found, you will likely need to replace the faulty sensor (either the CKP or CMP sensor) after testing them with a multimeter.
How much does it cost to fix P0375?
The cost to fix P0375 yourself is typically $50-$200 for a new crankshaft or camshaft position sensor. If you take it to a shop, expect to pay $150-$500, which includes parts and labor.
P0375 keeps coming back - why?
P0375 keeps coming back because the root cause was not fully addressed. This often happens if you replaced the wrong sensor, there's still a wiring issue, or a rare problem like a damaged tone ring or a failing engine computer is present.
Will P0375 fail emissions/smog test?
Yes, P0375 will cause your vehicle to fail an emissions or smog test. The Check Engine Light will be on, and the engine's timing issues will likely lead to elevated emissions.
What's the difference between P0375 and P0335?
P0335 indicates a general malfunction in the Crankshaft Position Sensor 'A' circuit, meaning the engine computer isn't seeing any signal or an incorrect signal. P0375 specifically points to a malfunction in the 'high resolution signal B' for timing reference, which is a more specific type of signal error, often related to the camshaft position sensor or a secondary crankshaft signal.
P0375 on Ford F-150?
On a Ford F-150, P0375 often points to a failing crankshaft or camshaft position sensor. These sensors are critical for the engine's timing, and their failure can lead to rough running or a no-start condition. Always check wiring first before replacing sensors.
Questions to Ask Your Mechanic
Did you check the live data for both the crankshaft and camshaft position sensor signals?
Good answer: Yes, I monitored both signals and saw a flat line or erratic readings from the 'B' signal, confirming the sensor or its circuit is faulty.
What did you find when inspecting the wiring harness to the affected sensor?
Good answer: I thoroughly checked the wiring for any chafing, corrosion, or breaks, especially near the sensor connector, and confirmed continuity.

Intermediate - requires basic hand tools, a multimeter for testing, and an OBD-II scan tool with live data capability to accurately diagnose which sensor is at fault.
Cost of Waiting
Ignoring P0375 can lead to severe engine misfires, stalling, and a no-start condition. Continued misfires send unburned fuel into your exhaust, which can rapidly destroy your catalytic converter ($800-$2,500 repair). A $50-$200 sensor replacement now prevents a much larger bill later.
While You're In There...
If accessing the sensor requires draining oil or is near oil passages, it's a good time for an oil change to ensure optimal sensor operation and engine health.
If the camshaft position sensor is located under the valve cover, replacing the gasket prevents future oil leaks and saves on repeat labor.
Tools You'll Need
- Basic socket set
- Wrench set
- Multimeter
- OBD-II scan tool with live data capability
- Screwdrivers
- Wire strippers/crimpers (if wiring repair is needed)
P0375 is a common sensor-related issue. Most repairs involve replacing a sensor, which is a straightforward job for an intermediate DIYer, and your engine will run smoothly again.

Your Next Steps
Step 1: Visually inspect the wiring harnesses and connectors for both the crankshaft and camshaft position sensors. Look for frayed wires, corrosion, or loose connections.
Step 2: If the visual inspection doesn't reveal the problem, use an OBD-II scan tool to check for other related codes and monitor live data from both sensors. Look for erratic or missing signals.
Step 3: Based on your diagnostic findings, replace the faulty crankshaft or camshaft position sensor. If wiring damage is found, repair it using appropriate connectors and heat shrink.
