Common causes include a bad cooling fan motor or a faulty cooling fan relay. Less common causes include corroded or loose electrical connectors, a faulty engine coolant temperature sensor, and open or shorted electrical wiring (often resulting in a blown fuse). How do you troubleshoot P0493 ? Look for damage to the tank indicating impact that may have damaged the fuel pump or sender. If the engine displays a miss and there wasn't a code, determine which cylinder is misfiring. If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port. Water will evaporate immediately on good cylinders and slowly on the missing cylinder. If this can't be accomplished pull the plugs and check the condition. Now, clear the codes and test-drive the vehicle to see if the code is reset. Searches related to P0493 - Fan Overspeed peugeot partner p0493 p0493 trailblazer
