Parts for your 2020 Haval H6-Camshaft sensor

2020 Haval H6 Camshaft Sensor: Purpose, care and when to replace

Yes, the 2020 Haval H6 is fitted with a camshaft position sensor (CMP). Technical references that confirm this include the GWM/Haval H6 workshop manual for the 1.5T and 2.0T petrol engines, which lists a Hall‑effect camshaft sensor mounted at the cylinder head, and the Bosch/Delphi engine management used on these engines that relies on CMP input for sequential fuel injection and variable valve timing. Common OBD‑II diagnostics in the H6 also include CMP‑related DTCs such as P0340/P0341, as outlined by standard OBD‑II service information.

On the H6, the camshaft sensor works with the crank sensor to tell the ECU exactly which cylinder is on its compression stroke. That lets the ECU time spark and fuel precisely and control the variable valve timing for better power, smooth idle, clean emissions and decent economy. Without a clean signal, the engine can crank longer, run rough, use more fuel and fall back into a limp strategy.

It isn’t a scheduled service item, but it does benefit from some simple care. Keep oil changes on time with the right spec so varnish and sludge don’t build up in the head area. Under the bonnet, check the sensor connector for oil ingress, broken locking tabs or green corrosion, and make sure the wiring loom isn’t rubbing on the cover. If the engine has timing chain stretch or a lazy VVT actuator, the ECU may flag cam/crank correlation faults even though the sensor itself is fine—worth keeping in mind during diagnosis.

Replacement is straightforward for most home mechanics:

• Disconnect the battery negative and remove the engine cover.
• Unplug the CMP connector, remove the retaining bolt and withdraw the sensor.
• Lightly oil the new O‑ring, seat the sensor squarely and refit the bolt and plug.
• Clear codes, then road‑test and check live data for stable cam angle.

When choosing a replacement, stick with genuine or quality OE‑equivalent parts matched to the H6’s engine code. If a new sensor doesn’t clear P0340/P0341, check the crank sensor, wiring continuity and mechanical timing before throwing more parts at it.

Typical signs a 2020 H6 camshaft sensor needs attention include hard starting, rough idle, hesitation, higher fuel use, reduced power, and a check‑engine lamp with cam sensor or cam/crank correlation codes.

Popular questions about 2020 Haval H6 camshaft sensors

Does the 2020 Haval H6 actually have a camshaft sensor?
Yes. The H6’s petrol turbo engines use a Hall‑effect camshaft position sensor for sequential injection and variable valve timing control. This is documented in the Haval H6 workshop manual and reflected in its OBD‑II diagnostics, which include CMP‑related fault codes.

What symptoms point to a failing camshaft sensor on a 2020 H6?
Owners typically notice longer cranking, rough idle, misfires, flat spots on acceleration, poorer fuel economy and a check‑engine lamp. Scan tools often show codes like P0340 or P0341. Similar symptoms can also come from wiring damage, a lazy VVT solenoid or timing chain issues, so diagnosis matters.

Can the H6’s camshaft sensor be cleaned, or should it be replaced?
If the issue is light oil contamination at the connector or sensor tip, a careful clean and securing the connector can help. However, internal sensor faults aren’t repairable—replacement is the go. Always rule out harness faults and mechanical timing problems before replacing the sensor.
