Introduction To MR299300 MAP Sensor
The MR299300 is an OEM-standard 3-pin intake manifold absolute pressure (MAP) / boost pressure sensor engineered for turbo-diesel applications. It is designed to deliver real-time manifold pressure data to the ECU/ECM, supporting precise air-fuel metering, stable turbo boost modulation, and efficient combustion on turbocharged engines.
Primary fitment is concentrated for Mitsubishi turbo-diesel platforms, including for the Pajero / Montero (V60, V3W, V6W, and related generations), for the L200 / Triton (K60T, K74T), and for the Pajero Sport / Montero Sport equipped with 2.5 TD / 2.5 TDi and 3.2 DiD engines. It is also commonly listed for the Volvo S40 and V40 in cross-reference catalogs; buyers are advised to confirm fitment against the original OE number before ordering.
Common failure symptoms addressed by this replacement include rough idle, hard starting (particularly when warm), hesitation or flat spots under acceleration, increased fuel consumption, and an illuminated check engine light. Related diagnostic trouble codes frequently include P0106 (MAP circuit range/performance), P0107 (MAP circuit low input), and P0108 (MAP circuit high input).

Professional Installation & Diagnostic Guidelines
- Pre-Installation Safety: Turn off the engine ignition switch and disconnect the vehicle’s negative battery terminal before disconnecting any electrical wiring.
- Locate the Sensor: Find the MR299300 sensor mounted on the firewall, inner fender apron, or intake manifold bracket on for Mitsubishi Pajero, Montero, L200, or Galant models.
- Inspect Vacuum Line: Carefully disconnect the rubber vacuum hose from the sensor nipple. Check the hose for splits, hardening, soft spots, or internal oil sludge clogging. Replace damaged vacuum tubing.
- Disconnect & Unbolt: Squeeze the locking tab on the 3-pin electrical connector and disconnect the wiring harness. Remove the single mounting bolt securing the metal bushing bracket.
- Install New Sensor: Fasten the new MR299300 sensor using the original mounting bolt (torque to approx. 6.0 – 8.0 Nm). Reattach the vacuum hose firmly onto the barb port, ensuring a tight leak-free fit.
- Reconnect & Clear Codes: Connect the 3-pin wiring harness until the latch clicks securely. Reconnect the battery terminal, start the engine, verify smooth idle operation, and use an OBD-II diagnostic scanner to clear any stored historical DTCs.

FAQ
Q1: How is the MR299300 sensor mounted and connected compared to manifold push-in sensors?
A: Unlike push-in MAP sensors that seat directly into a hole in the intake plenum with an O-ring, the MR299300 uses a remote bracket mount with a single metal-sleeved bolt hole. It is fastened to the vehicle’s firewall or an intake bracket and connected to the intake manifold vacuum port via a flexible rubber vacuum hose. This remote design protects the sensing diaphragm from direct manifold heat soak and excessive crankcase oil accumulation.
Q2: What specific OBD-II diagnostic fault codes (DTCs) indicate a failing MR299300 sensor?
Q3: Are part numbers MR299300, E1T16671, and E1T16671A completely interchangeable?
A: MR299300 is a widely referenced part number for Mitsubishi applications, while E1T16671A, E1T16671, and E001T16671A are alternative cross-reference numbers commonly associated with this sensor. They share identical 3-pin electrical pinouts, mounting dimensions, pressure response curves, and vacuum nipple fittings.
