Product Information
Full details
The CI MAP Sensor (XMAP539) is a precision-engineered replacement component designed for automotive enthusiasts and technicians looking to restore accurate air-fuel ratio management in compatible Honda and Rover vehicles. By providing real-time intake manifold pressure readings to the Engine Control Unit, this sensor ensures smooth idling and optimal throttle response, though users should note that improper installation or pre-existing vacuum leaks may negate the performance benefits of a new sensor.

FAQs
How do I know if my MAP sensor is faulty?
Common signs include poor fuel economy, engine hesitation, hard starting, or a Check Engine Light indicating a sensor circuit fault.
Can I use this on a non-Honda vehicle?
This sensor is compatible with specific OEM references listed, including those used by Rover, Triumph, and Austin. Please verify your specific part number against the OEM references provided.
Does the sensor require calibration?
No, this is a plug-and-play sensor; however, resetting your ECU by clearing codes after installation is highly recommended.
What is the operating range of the sensor?
The sensor is designed to measure pressures ranging from 10000 Pa to 170000 Pa.
Is any special sealant needed during installation?
No, you should use the provided O-ring seal. Using liquid sealants can damage the sensor or cause vacuum leaks.
Why is the sensor failing so soon after replacement?
Premature failure is often caused by excessive heat, vibrations, or oil/fuel contamination entering the sensor port. Check your intake system for excessive blow-by.
Troubleshooting
Engine continues to idle poorly after installation
Check all intake manifold vacuum hoses for leaks or cracks, as the sensor only reports pressure that exists in the manifold.
Check Engine Light remains on
Clear the diagnostic trouble codes (DTCs) using an OBD-II scanner after the new sensor is installed to reset the ECU memory.
Sensor plug does not fit securely
Inspect the wiring harness connector for bent pins or corrosion that may prevent the CI XMAP539 from seating properly.
Pros and Cons
Pros
- High accuracy across a wide pressure range
- Direct fit for multiple OEM reference numbers
- Essential for restoring correct air-fuel mixtures
- Plug-and-play installation design
Cons
- Requires specific vehicle compatibility verification
- Sensitive to vacuum leaks in the intake system
- Electrical harness condition affects sensor performance
Setup, Compatibility & Care
Before installation, ensure the vehicle engine is cool and the ignition is switched off. Locate the original MAP sensor on the intake manifold, disconnect the 3-pin harness, and remove the retaining screws. Ensure the O-ring seal is seated correctly during installation of the new sensor to prevent vacuum leaks. This unit is compatible with Honda references 37830P05A01, 37830P0GS00, 37830P7AN11, 37830PAAS00, and Rover MHK100590. To maintain the sensor, keep the electrical connector free of oil and debris, and inspect the intake vacuum lines periodically for cracks or brittleness.
