Extended Product Information
FAQs
What does a MAP sensor do?
A Manifold Absolute Pressure (MAP) sensor measures the air pressure in the intake manifold. This information is crucial for the Engine Control Unit (ECU) to calculate the correct amount of fuel to inject for optimal engine performance and efficiency.
What vehicles is this MAP sensor compatible with?
This sensor is designed for specific Mercedes and Jeep models. It also cross-references with numerous OEM and aftermarket part numbers. Always verify compatibility with your vehicle's VIN or existing part number.
Can I install this sensor myself?
While some DIY enthusiasts may attempt installation, it is highly recommended to have it done by a qualified mechanic to ensure proper fitment, connection, and potential recalibration.
What are the signs of a failing MAP sensor?
Common symptoms include a check engine light, rough idling, poor acceleration, decreased fuel economy, stalling, and issues with emissions.
What is the pressure range of this sensor?
The pressure range for this CI MAP Sensor XMAP514 is from 34400 Pa to 315600 Pa.
How do I know if I need to replace my MAP sensor?
A diagnostic scan tool is typically used to read trouble codes related to the MAP sensor (e.g., P0105, P0106). Visual inspection and monitoring sensor data can also help diagnose a faulty sensor, along with observing the symptoms mentioned previously.
What is the difference between a MAP sensor and a MAF sensor?
A MAP sensor measures pressure in the intake manifold, while a Mass Air Flow (MAF) sensor measures the *mass* of air entering the engine. Both are important for air-fuel mixture calculations, but they measure different parameters.
Troubleshooting
Check Engine Light (CEL) remains on after installation
Ensure the sensor is correctly seated and the electrical connector is fully plugged in. Verify that the correct part number was installed. Some vehicles require a reset of the ECU or a specific relearn procedure using a diagnostic tool.
Engine performance issues persist (e.g., rough idle, poor acceleration)
Confirm the sensor is functioning correctly by checking live data with a diagnostic scan tool. Inspect the vacuum line connected to the sensor for leaks or blockages. Ensure no other engine issues are present.
Sensor connector does not fit properly
Double-check the compatibility for your specific vehicle model and year. Ensure you have the correct CI MAP Sensor XMAP514 and that no pins are bent on either the sensor or the vehicle's wiring harness.

Setup, Compatibility & Care
Compatibility Verification:
Before installation, confirm that the CI MAP Sensor XMAP514 is compatible with your specific Mercedes or Jeep model by checking your vehicle's existing part number against the cross-reference list (e.g., CHRYSLER 5117545AA, 5117545AB, JEEP 5117545AA, BOSCH 0 261 230 193).
Installation:
Installation typically involves locating the MAP sensor on the intake manifold, disconnecting the electrical connector, removing the mounting fastener, and replacing the old sensor with the new one. It is highly recommended to have this part installed by a qualified automotive technician. Proper torque on the mounting fastener and secure connection of the electrical plug are essential. Some vehicles may require a scan tool to clear error codes or perform a sensor relearn procedure after replacement.
Care:
MAP sensors are generally maintenance-free. Avoid spraying cleaning agents directly onto the sensor. If the sensor's electrical connector appears dirty, clean it gently with an appropriate electrical contact cleaner. Ensure the intake manifold area is clean before installing the new sensor to prevent debris from entering the engine.
