3858212 — 3 Wire Trim Position Sensor 3858212 21652399 For Volvo Tsk Sx-M Sx-Mda Sx-Mdc Sx-Mlt

This 3-wire trim position sensor provides the engine control module with precise feedback on the throttle pedal's position, crucial for accurate throttle control and engine response. Manufactured to meet stringent OEM standards, it ensures reliable and consistent signal transmission, unlike a worn sensor that may produce erratic or intermittent readings. Operators might experience inconsistent throttle response, hesitation during acceleration, or the illumination of the check engine light.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A faulty trim position sensor can lead to inconsistent engine performance, such as hesitation during acceleration or an inability to reach full throttle. If ignored, the engine may run rough, stall unexpectedly, or enter a reduced power mode, impacting operational capability. Continued use with a faulty sensor can lead to increased fuel consumption and potential damage to the engine control system.

Installation Tip

Ensure the engine is off and the throttle linkage is in the closed position before removing the old sensor. When installing the new sensor, ensure it is correctly aligned with the throttle shaft and securely fastened to prevent movement.

Service Note

When replacing the throttle position sensor, inspect the throttle cable or linkage for smooth operation and proper adjustment.
