For the 4 cyl 2.5L engine will this work as a camshaft and a crankshaft sensor? Meaning i need to order two of the same one for camshaft and one for crankshaft? 🤔
Pedro G December 29, 2017
Yes, you would need to order a quantity of 2 to replace both camshaft and crankshaft position sensors. The 2.5L engine models used the same sensor for both positions.
