Codes p0722 and p0717 what is the problem? - 2003 Suzuki Aerio

P0722 stands for output speed sensor, this sensor might be in need of replacement, p0717 is for transmission turbine speed sensor, P0717 code comes with the following symptoms: engine cutting out, misfire and hard start after the engine is warmed up. check the coil plugs which is the equivalent of spark plugs except it does not have any plug wires. Start with the mileage and if the engine has over 100k miles, usually the coil plugs are worn. You can check it by checking the coil plug wells on the valve cover. If soaked with oil, the coil plug is normally shot and this goes the same for the valve cover gasket. Apparently, when the valve cover leaks oil, it is deposited in the coil plug well and starts shorting the coil plugs because of the contaminated oil. Note: when changing coil plugs, always replace them ALL as a set.
