2017 Haval H6 MAP Sensor — What it does, where it lives, and how to look after it

Technical sources confirm the 2017 Haval H6 does use a MAP sensor. The Haval/Great Wall workshop manual for the GW4G15B 1.5‑litre turbo petrol and diesel variants lists an intake manifold absolute pressure (MAP) or “boost pressure” sensor, and the factory diagnostic trees include MAP‑related DTCs (P0106–P0108). Bosch MED17 engine management references for these engines also describe a T‑MAP (pressure and temperature) sensor used for load and boost control. Parts catalogues for the H6 further enumerate a boost/MAP sensor fitted to the intake manifold or charge pipe.

On this model, the MAP sensor measures the absolute pressure in the intake manifold so the ECU can work out engine load. That info helps it dial in fuelling, ignition timing and turbo boost, and it also compensates for altitude and temperature. Many H6s run both a MAF (on the airbox inlet) and a T‑MAP on the manifold or intercooler pipe, giving the ECU a more accurate picture of air mass and boost.

There’s no fixed replacement interval for the MAP sensor, but it’s smart to inspect it during routine servicing (every 20,000–30,000 km). If the H6 feels doughy off the line, drinks more fuel than usual, idles rough, or throws the check‑engine light with codes like P0106, P0107 or P0108, the MAP is a usual suspect.

• Location: typically on the intake manifold or charge pipe, held by one or two screws, with a 3‑ or 4‑pin plug. Don’t confuse it with the MAF near the air filter.
• Quick checks: look for split boost hoses, oil contamination in the plug, chafed wiring, or a hardened O‑ring. Any vacuum reference hose (if fitted) should be crack‑free.
• Cleaning: remove the sensor and mist the tip with electronics or MAF‑safe cleaner. No scraping, no cotton buds, and avoid high‑pressure air. Let it dry fully before refitting.
• Replacement: disconnect the battery, swap the sensor and O‑ring, nip the bolts to light torque, reconnect, clear fault codes, and perform an idle relearn if needed. A quick road test under boost confirms it’s happy.

Look after the air filter, keep the intake plumbing airtight, and the H6’s MAP sensor will usually go the distance without drama.

Popular questions

Where is the MAP sensor on a 2017 Haval H6?
It’s normally mounted on the intake manifold or the intercooler charge pipe close to the throttle body. Look for a small black sensor with a multi‑pin connector and an O‑ring seal. The MAF lives upstream at the airbox, so don’t mix the two up.

What are the symptoms of a bad MAP sensor on an H6?
Common signs are sluggish acceleration, higher fuel use, a rough idle, black smoke on boost, and a check‑engine light with codes like P0106, P0107 or P0108. Because the ECU relies on MAP for load and boost control, faults can feel like a boost leak.

Does the 2017 H6 have both MAF and MAP?
Yes, many 1.5T H6s use a MAF at the airbox and a T‑MAP on the manifold/charge pipe. The ECU cross‑checks both to manage fuelling and turbo pressure accurately across different conditions.
