The camshaft positioning sensors determines the rotating position of the camshaft to regulate spark timing and fuel injector operation in sync with the crankshaft sensors. This set replaces the bank 1 passenger side and bank 2 driver side camshaft sensors of your vehicle. If you are experiencing rough idle, hard to start, stalling, hesitation, decrease in engine performance and a check engine light with codes P0340 & P0345, then you may have to replace your camshaft position sensors. The sensor that has an angled connector is the bank 2 sensor. These sensors can easily be located behind the engine near the firewall. Bank 1 is on the passenger side and Bank 2 ( Angled Sensor ) is located on the driver side of the engine depending on the model of your vehicle.
