Parts for your 2022 Haval H6-Camshaft sensor

2022 Haval H6 camshaft sensor: what it does and how to look after it

Technical references confirm the 2022 Haval H6 uses a camshaft position sensor (CMP). The GWM/Haval H6 Workshop Manual (2021–2023, Engine Control System), the GWM Electronic Parts Catalogue for GW4C20B (2.0T petrol) and GW4B15D-based hybrid engines, and Haval OBD-II fault listings (which include CMP-related codes such as P0340/P0341) all specify a camshaft sensor on these engines.

On the 2022 H6, the camshaft sensor is a small, solid-state unit that reads a toothed target on the camshaft to tell the ECU exactly where the intake valve timing sits. That position data is critical for quick starts, smooth idle, accurate sequential fuel injection, spark timing, and variable valve timing (VVT) control. If the CMP signal drops out, the H6 can usually limp by estimating timing from the crank sensor, but the result is rough running, a check engine light, poor fuel economy and sometimes hard starting.

Owners will typically find the CMP mounted on the cylinder head near the timing cover (under the plastic engine cover). The ECU uses it constantly, so while it’s not a scheduled service item, it’s worth a quick look during routine servicing. Keep an eye out for oil weeping into the connector, heat-baked wiring, or loose terminals. Sticking to the correct engine oil spec and intervals also helps VVT actuators behave, which reduces the chance of spurious cam correlation faults.

Replacement is straightforward for a competent DIYer or technician: disconnect the battery, unplug the connector, undo the single retaining bolt, twist the sensor out, lube the new O-ring with a dab of clean engine oil, seat it fully and tighten the bolt to light torque (around 8–10 Nm, always confirm for the exact engine). After refit, clear fault codes and, if the scan tool allows, run a cam/crank relearn. Before condemning the sensor, rule out wiring damage, oil contamination in the plug, and timing issues. Using a genuine or high-quality equivalent sensor that matches the OE spec is the safe bet.

Common symptoms of a crook camshaft sensor on an H6 include:

• Check engine light with codes like P0340/P0341/P0344
• Hard starting, rough idle, flat spots, higher fuel use
• Occasional stalling or reduced power

With a clean connector, healthy loom, and the right oil changes, most H6 cam sensors live a long, drama-free life. When they do fail, they’re usually quick to diagnose and replace.

FAQs

Where is the camshaft sensor on a 2022 Haval H6?
It’s typically on the cylinder head near the timing cover, accessed by removing the plastic engine cover. On the 2.0T, look at the intake side of the head, for the hybrid, access is similar but space is tighter around the DHT components.

Does the 2022 H6 have one or two camshaft sensors?
Every 2022 H6 has at least one CMP sensor. Depending on engine and market, some variants may use additional sensing. The quickest way to verify for a specific VIN is via the GWM parts catalogue or the workshop manual.

Should the camshaft sensor be replaced as routine maintenance?
No. It’s a monitor-and-replace-on-fault item. Include a visual check of the plug and loom during regular services and only replace the sensor if diagnostics and fault codes point to it.
