Keep spark and injection timing on-point with the Walker Products Engine Crankshaft Position Sensor 1008-1015. It drops in as a direct-fit replacement for the listed heavy-duty applications, including the 2011-2015 MACK CXU, GU7, GU8, LEU and MRU, plus the 2011-2014 VOLVO 9700, 2011-2015 VOLVO VAH and VHD, 2011-2016 VOLVO VNL, and 2012-2016 VOLVO VNM.
This sensor monitors the position and rotational speed of the crankshaft and reports that signal to the engine control module, which the ECM uses to help schedule ignition timing and fuel injection.
- Direct-fit replacement: installs in place of the original sensor on the listed applications.
- Reads crankshaft position & speed: supplies the reference signal the ECM relies on for timing and injection control.
- Plug-in replacement: intended to restore the original sensor's electrical function.
Signs the original sensor may need replacing include hard starting, a no-start condition, stalling, intermittent misfire, or hesitation. If a failed crankshaft position sensor is the cause, replacing it with this unit addresses that component; diagnose the cause before ordering, since these symptoms can have other sources.
