Got a check engine light for camshaft or crankshaft position on your 2002-2008 Infiniti or Nissan with the 3.5L V6 engine (like the G35, 350Z, Altima, etc.)? This set has you covered – it includes ALL THREE sensors you'll likely need! That's usually two camshaft position sensors and one crankshaft position sensor. They're brand new from CarBole and come with a manufacturer's warranty. The set includes sensors matching part numbers like PC460, PC461, PC499, 23731AL61A, and 237316J90B. The manufacturer part numbers listed are 23731AL61A, 237314M506, and 237317Y000. They're front engine placement sensors. No UPC applies. These sensors are critical for your engine's timing and fuel injection; when they fail, you might get rough running, stalling, or a no-start condition. Buying them as a set is smart because if one is failing, the others might be close behind. Replacing all three at once saves you time and labor down the road. A must-have for any DIY mechanic or shop working on these super common VQ35 engines. Get your car running smoothly again!
