NGK Crankshaft Position/Pulse Sensor CHN3-V044 | NGK 81043 | Fits BMW E36

NGK CHN3-V044 Engine Timing Pick-up – Part No. 81043

Restore crisp starting, smooth idle and clean throttle response with NGK’s CHN3-V044 engine position pick-up, part number 81043. This premium NGK unit sends a clean, stable RPM and position signal to the ECU for accurate ignition synchronisation, helping cure hot no-start, random cut-outs and erratic rev readings that often point to a tired crank angle sender.

We run these sensors on our own cars and customer vehicles and they have been spot-on for reliability and fit. If you are chasing intermittent stalling, misfires at idle or hesitation under load on your BMW or Rover 75, this NGK solution is a proper plug-and-play fix.

Why this NGK sensor is a smart upgrade

• NGK quality for a clean, consistent engine speed signal to the ECU
• Direct-fit plug design with factory-style connector and secure mounting
• Built to handle heat and vibration inside the bay for long service life
• Helps resolve poor starting, rough idle and intermittent cut-out when caused by a failing crank signal sender
