IV. Key Fitment & Function Notes
-
Fitment Verification:
- Confirm your vehicle’s chassis code (E30/E36), production period, and engine model match the above list. For example, BMW 325i (E36) must use M50 B25 engine (1990–1995) to ensure compatibility.
- Cross-check the original sensor’s OE number (13631721456 or 13631726591) with this product to avoid mismatches.
-
Critical Function:
The TPS detects the throttle’s opening angle and transmits real-time data to the ECU. This data is used to adjust fuel injection quantity and ignition timing, directly affecting engine performance, fuel efficiency, and idle stability. A faulty TPS may cause rough idling, delayed acceleration, or increased fuel consumption.
-
Installation Tips:
- No cable is included—reuse the original vehicle wiring harness to ensure electrical compatibility.
- Align the 2 mounting holes with the throttle body’s fixing points; improper installation may damage the sensor or throttle body.
- Professional installation is recommended, especially for BMW’s precision engine control system.
