Parts for your 2019 Haval H6-Crank angle sensor

2019 Haval H6 crank-angle sensor: what it does, where it lives, and how to look after it

Based on factory service literature for the 2017–2020 Haval H6 (covering the GW4G15B 1.5T and GW4C20B 2.0T petrol engines) and multiple aftermarket parts catalogues/EPC listings, the 2019 Haval H6 is fitted with a crankshaft position sensor, commonly called a crank-angle sensor (CKP). It’s a core input for the engine control module and is absolutely relevant to this model.

On the 2019 H6, the crank-angle sensor tracks the crank’s exact position and speed so the ECU can time fuel injection, ignition, and run diagnostics like misfire detection. Without a clean signal the H6 can be hard to start, stall at idle, feel down on power, or throw faults such as P0335–P0339. It also helps the ECU coordinate cam timing on variable valve timing engines, so accuracy matters for smooth, efficient running.

There’s no set replacement interval for a CKP on the H6, it’s a “replace-on-fault” item. That said, a quick look during routine servicing goes a long way. Common sense checks include making sure the connector is snug, free of oil wicking, and the harness isn’t rubbing on the bellhousing or near the turbo. If removing the sensor, keep the magnetic tip clear of metal filings and grit.

Depending on engine variant, the sensor is typically mounted at the transmission bellhousing or at the front of the block reading a reluctor on the crank. Replacement is straightforward for a competent technician:

• Disconnect the battery, unplug the sensor, remove the retaining bolt, and gently extract the sensor.
• Lightly oil the O-ring on the new unit, seat it square, and tighten the bolt to manufacturer torque (small fastener—don’t overdo it).
• Clear fault codes and perform a CKP/idle relearn with a scan tool if required.

Owners in Australia and New Zealand often ask about cost and downtime: genuine or quality OEM-equivalent sensors are affordable, and fitting usually takes under an hour if access is good. If the H6 is showing intermittent stalling or long crank when hot, testing the CKP signal with a scope and checking for heat-soak–related wiring faults is a smart first step before parts swapping.

Pro tips for longevity:

• Keep oil leaks in check—oil contamination can creep into connectors.
• After any clutch/gearbox or front-seal work, verify the harness routing and sensor clearance.
• Use quality parts, poor tolerances can cause false misfire flags and rough running.

Where is the crank-angle sensor on a 2019 Haval H6?

On most H6 petrol variants it’s mounted low on the engine, either at the transmission bellhousing reading the flywheel/reluctor ring or at the front of the block reading a tone wheel on the crank pulley. Access varies by engine and trim, a lift makes the job easier.

What are the signs the H6 crank-angle sensor is failing?

Classic symptoms include hard starting, sudden stalling at idle, a dead tach during crank, reduced power, and engine light with codes like P0335. Heat-soak faults are common—runs fine cold, plays up hot—so testing when warm helps pin it down.

Does the crank-angle sensor need regular servicing or calibration?

There’s no routine service interval. Inspect the connector and wiring during scheduled servicing, especially after any oil leak. If the sensor is replaced, a code clear and sometimes a relearn with a scan tool are recommended to ensure crisp starts and stable idle.
