Frequently Asked Questions
What does P0395 mean?
P0395 indicates that your vehicle's engine computer has detected an intermittent electrical problem with the Camshaft Position Sensor 'B' on Bank 2. This sensor helps the computer know the exact position of the camshaft for proper engine timing.
Can I drive with P0395?
Yes, for short trips only. You can drive your vehicle for essential, short trips, but be aware that the engine might stall unexpectedly, have reduced power, or experience hard starting. Fix this code within a few days to prevent further issues.
Will P0395 clear itself?
No, P0395 will not clear itself. While the Check Engine Light might turn off if the intermittent fault temporarily resolves, the underlying issue remains. The code will return, and the problem will persist until the faulty component is repaired or replaced.
How do I fix P0395 myself?
Start by inspecting the wiring and connector for the Camshaft Position Sensor 'B' on Bank 2. If they look good, you will likely need to replace the camshaft position sensor itself. This usually involves disconnecting the electrical connector, unbolting the old sensor, and installing the new one.
How much does it cost to fix P0395?
A DIY fix for P0395 typically costs $30-$150 for a new camshaft position sensor. If you take it to a professional shop, expect to pay $150-$450, which includes the part and 1-2 hours of labor.
P0395 keeps coming back - why?
If P0395 keeps returning, it often means the initial repair didn't address the root cause. This could be due to a faulty replacement sensor, an overlooked wiring issue further up the harness, a problem with the crankshaft position sensor, or, in rare cases, an issue with the engine's computer.
Will P0395 fail emissions/smog test?
Yes, P0395 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on automatically results in a failure in most states, and an intermittent sensor issue directly impacts engine timing and emissions control.
What's the difference between P0395 and P0345?
P0395 indicates an intermittent circuit issue with Camshaft Position Sensor 'B' on Bank 2. P0345 indicates a general circuit malfunction with Camshaft Position Sensor 'A' on Bank 2. The 'B' sensor typically refers to the exhaust camshaft, while 'A' refers to the intake camshaft, and 'intermittent' means the problem comes and goes.
P0395 on Ford F-150?
On many Ford F-150 models, especially those with V8 engines, there are multiple camshaft position sensors. P0395 specifically points to the 'B' sensor on Bank 2. This sensor is often located near the rear of the cylinder head on the passenger side. Wiring issues are common on older F-150s, so inspect the harness thoroughly.
Questions to Ask Your Mechanic
Did you check the wiring harness and connector for the Bank 2 Camshaft Position Sensor 'B' for any damage or corrosion?
Good answer: Yes, I thoroughly inspected the wiring and connector. I found no visible damage or corrosion, and I tested for continuity and proper voltage.
What were the live data readings for the Camshaft Position Sensor 'B' on Bank 2 when the fault occurred?
Good answer: The live data showed an intermittent drop in signal or an erratic signal pattern from the sensor, confirming the sensor itself or its circuit is failing intermittently.

Intermediate - requires basic hand tools and a multimeter for proper diagnosis. Access to a scan tool is a significant advantage.
Cost of Waiting
Ignoring an intermittent P0395 can lead to your engine stalling unexpectedly, creating a dangerous situation. If the sensor fails completely, your engine will not start. Continued poor engine timing can also lead to increased wear on internal engine components over time, potentially causing more expensive repairs down the road.
While You're In There...
Cleaning the electrical connector pins can resolve intermittent contact issues without replacing parts.
If you find damaged wiring, a repair kit allows you to splice in new wire sections, preventing future intermittent issues.
Tools You'll Need
- Basic hand tools (sockets, wrenches)
- Multimeter
- Wire brush (for cleaning connectors)
- Electrical contact cleaner
- Scan tool (optional, but highly recommended for diagnostics)
P0395 is a common sensor code. Most repairs involve replacing an accessible sensor or fixing a simple wiring issue, and your engine will run smoothly again afterward.

Your Next Steps
Step 1: Perform a thorough visual inspection of the Camshaft Position Sensor 'B' (Bank 2) and its wiring. Look for any obvious damage, corrosion, or loose connections. Clean the connector with electrical contact cleaner.
Step 2: If the visual inspection doesn't reveal the problem, use a multimeter to test the sensor's resistance and voltage output. Compare your readings to your vehicle's service manual specifications.
Step 3: If the sensor tests faulty or if the wiring is damaged, you'll likely need to replace the Camshaft Position Sensor 'B' (Bank 2) or repair the wiring harness.
