Speedometer Sensor Volvo 900

A sudden engine stop or a car that cranks without firing can point to a tired Impulse Sensor at the flywheel. This flywheel sensor reads RPM and crankshaft position for the Control Unit and is a common checkpoint for intermittent starting problems on the Volvo 900, for example the 940. This group gathers Impulse Sensors that fit the 900 series – check the connector and wiring harness against your model year when replacing.
