Description
The 20513343 is a Mack/Volvo engine speed (tachometer) sensor with a 2-pin rectangular connector and Viton 75 O-ring, mounted at the flywheel housing on the MP7/MP8 and Volvo D11/D13/D16 platform to read the crankshaft target wheel and feed RPM to the ECM and instrument cluster. PAI 845069 is the catalog equivalent and replaces Mack/Volvo 20513343 and 21426987.
Signs You Need a New Speed Sensor
- Tachometer drops to zero or jumps erratically while running
- Engine cranks but fails to start, or stalls intermittently
- Active engine speed sensor fault code on the dash
- Loss of cruise control or speed-limiter function
- Hard or rough starts when the sensor signal is intermittent
