Ford Transit-350 HD Engine Camshaft Position Sensors
Ford Transit-350 HD Engine camshaft position sensors
Engine camshaft position sensors for the Ford Transit-350 HD start at $10.95, and AutoBuffy stocks 15 options from GPD, Delphi, and Denso. The camshaft position sensor tells the ECU exactly where the camshaft is in its rotation so fuel injection and ignition timing stay synchronized. When it fails, the engine can stall, misfire, or refuse to start entirely.
Signs your Ford Transit-350 HD needs a new camshaft position sensor
- Check Engine light on with a stored P0340, P0341, P0345, or related camshaft position sensor fault code
- Engine cranks normally but will not start, especially after it has reached operating temperature
- Rough idle or random misfires that worsen under load or during acceleration
- Engine stalls unexpectedly at low speeds or at idle with no warning
- Noticeable hesitation or stumble when accelerating from a stop
- Reduced fuel economy caused by the ECU defaulting to a fixed, inefficient fuel and timing map
Which camshaft position sensor should you buy for your Ford Transit-350 HD?
The main decision is whether to buy an OEM-equivalent sensor, a direct-fit aftermarket unit, or a dealer-sourced OEM part. For most daily drivers, a quality direct-fit aftermarket sensor from a reputable brand matches OEM performance at a lower cost. On vehicles with variable valve timing (VVT/VVL) systems, signal accuracy matters more, so leaning toward OEM-spec parts is worth the extra investment.
OEM Replacement (Dealer Part)
Best for
Vehicles under warranty or with active VVT/VVTi systems where signal precision is critical
What you get
Exact factory fit, confirmed calibration, and manufacturer-backed quality — typically the highest price point
OEM-Equivalent Aftermarket (e.g., GPD, Delphi, and Denso)
Best for
Most daily drivers looking for reliable performance without dealer pricing
What you get
Direct plug-and-play fitment, meets or exceeds OEM signal specs, and usually includes a warranty
Economy / Value-Tier Aftermarket
Best for
High-mileage vehicles where budget is the priority and longevity expectations are modest
What you get
Lower upfront cost, acceptable short-term performance, but quality control and lifespan can vary
Multi-Position Kit (Bank 1 + Bank 2)
Best for
V6 and V8 engines with two camshaft position sensors that are both aging simultaneously
What you get
Replaces all sensors in one job, prevents a second labor visit soon after, often bundled at a discount

Replacing the camshaft position sensor on a Ford Transit-350 HD
Easy⏱ 30–60 minutesOBD-II scan tool (to read and clear fault codes)Socket set with extensionsFlathead and Phillips screwdriversConnector pick or small trim tool (to release wiring harness clip)Clean shop rags
The camshaft position sensor on most Ford Transit-350 HD applications is accessible from the top or front of the engine near the camshaft sprocket or timing cover, and replacement typically involves disconnecting the electrical connector, removing one or two retaining bolts, and pulling the sensor straight out. Lightly coat the new sensor's O-ring with clean engine oil before installation to ensure a proper seal and prevent tearing. After installation, use a scan tool to clear any stored codes and confirm no new faults appear after a short test drive.
Frequently asked questions
How much does it cost to replace camshaft position sensors on a Ford Transit-350 HD?
Parts for the Ford Transit-350 HD start at $10.95 at AutoBuffy. Add shop labor of roughly one to two hours at local rates and you are looking at a total repair cost that varies by location. Doing it yourself keeps the cost close to the part price alone, which is why this is a popular DIY repair.
Can I drive my Ford Transit-350 HD with a bad camshaft position sensor?
Driving with a failed camshaft position sensor is not recommended. The ECU may fall back to a fixed timing map, causing poor performance and higher fuel consumption. More critically, the engine can stall without warning in traffic, and on vehicles with variable valve timing the risk of incorrect cam phasing causing internal engine damage increases over time.
Will replacing the camshaft position sensor on my Ford Transit-350 HD clear the Check Engine light?
Yes, replacing a confirmed faulty sensor and clearing the code with a scan tool should extinguish the Check Engine light. If the light returns after replacement, check the wiring harness connector for corrosion or damage, verify the reluctor wheel on the camshaft is not damaged, and confirm no other fault codes are present alongside the cam sensor code.
How do I know if my Ford Transit-350 HD has one or two camshaft position sensors?
V6 and V8 engines typically have two camshaft position sensors — one per cylinder bank — while most inline four-cylinder engines use a single sensor. Check your fault code: P0340 and P0341 generally refer to Bank 1, while P0345 and P0346 point to Bank 2. Your vehicle-specific parts listing on AutoBuffy will also confirm how many sensors your engine requires.
Is the camshaft position sensor the same as the crankshaft position sensor on a Ford Transit-350 HD?
No, they are separate sensors with different jobs. The crankshaft position sensor monitors crankshaft speed and piston position, while the camshaft position sensor tracks camshaft position to sequence fuel injection and ignition. Both communicate with the ECU together, and a fault code for one does not automatically mean the other has failed, though worn sensors often degrade around the same mileage.
Does the camshaft position sensor need to be programmed after installation on a Ford Transit-350 HD?
Most camshaft position sensors are a direct swap requiring no programming — plug in the connector, clear the fault code, and drive. However, some late-model vehicles with advanced variable valve timing systems may require a relearn procedure using a scan tool after sensor replacement. Check your vehicle's service documentation or confirm with a scan tool before assuming the repair is complete.
