Keep ignition and fuel-injection timing dialed in across heavy-duty MACK and VOLVO trucks with the Walker Products Engine Crankshaft Position Sensor 1008-1015. It installs as a direct-fit replacement for the listed applications, including the 2011-2016 VOLVO VNL, 2012-2016 VOLVO VNM, 2011-2015 MACK CXU, GU7, GU8, LEU and MRU, plus the VOLVO 9700, VAH and VHD — see the Buyer's Guide tab for the full list.
- Core function: monitors the crankshaft's rotational position and speed and relays that signal to the engine control module so ignition and fuel-injection timing stay accurate.
- Direct fit: made to match the listed MACK and VOLVO applications for a straightforward install.
- Signs it may need replacing: hard starting or a no-start, stalling, rough running, or a check-engine light — diagnose the cause before replacing, since these symptoms can have other sources.
Fitment by engine: covers applications using the manufacturer engine codes 6-11.9L, 6-12.8L, L6-8.9L, L6-10.8L, L6-12.8L, L6-14.9L and L6-16.1L. If a failed crankshaft position sensor is the cause of your driveability issue, 1008-1015 replaces it.
