PS02 and PS04 MAP sensors are critical manifold absolute pressure spare parts developed specially for CNG and LPG sequential-injection autogas conversion systems. The sensor feeds real-time intake manifold pressure signals back to autogas ECU, so the controller can accurately adjust gas injection volume, optimize engine combustion performance and improve overall fuel economy. This pressure sensor is fully compatible with 4-cylinder CNG full conversion kits and most gas-system equipment among CNG & LPG spare-parts portfolio.
With high-precision sensing chip and strict factory quality control, PS02 / PS04 MAP sensors are widely used for petrol-to-LPG/CNG dual-fuel car retrofits. Factory-direct bulk wholesale is available with competitive pricing for autogas repair shops and auto-parts distributors worldwide.

Frequently Asked Questions
Q1: What is the function of PS02 / PS04 MAP sensor in autogas system?
A1: It collects real-time intake manifold pressure data and transmits signals to autogas ECU, so ECU can adjust gas injection amount for better combustion efficiency and fuel saving.
Q2: Can PS02 and PS04 be interchanged directly?
A2: Please confirm ECU requirements before replacement. Though appearance is similar, internal calibration parameters may differ for different ECU brands.
Q3: What symptoms indicate a faulty MAP sensor on dual-fuel vehicles?
A3: Abnormal gas consumption, unstable idle speed under gas mode, power drop or frequent ECU error codes are common signs of MAP-sensor failure.
Q4: Does this MAP sensor support taxi and high-mileage fleet vehicles?
A4: Yes. Shock-proof sealed housing is specially built for heavy-duty continuous operation scenarios like taxis and commercial fleets.
Q5: What does the 1-year factory warranty cover?
A5: One-year warranty covers manufacturing defects. Damage caused by wrong installation, water ingress, over-voltage or mechanical impact is excluded.
Q6: Do you accept factory bulk orders for PS02 PS04 MAP sensors?
A6: Yes, factory-direct bulk orders are supported with competitive pricing. OEM requirements can also be discussed for large-volume purchases.
