Question

I got the codes 118, 122, 327 on my 1995 Ford F350 5.8L

Answer 1

118 Engine coolant temperature circuit above maximum voltage

122 Throttle position(TPS) circuit below minimum voltage

327 Exhaust gas recirculation valve position sensor circuit above maximum voltage

When ever there is a code that states above maximum voltage the connector to the sensor is disconnected a reconnection or a wire connection repair is the solution the connection is open to the sensor. As for the TPS this is a common wear when it is below minimum it can no longer contribute to the engine management system
