P0122 2004 Jeep Liberty -

Question

If the throttle positioning sensor is faulty, will it cause the engine to completely disengage? Or will it simply result in worse gas mileage?

Answer 1

HI there,

Either can happen because if the TPS isn't working, the computer doesn't know what gear the transmission should be in. If it sticks in a lower gear it will affect the fuel mileage, It can also take it out of gear completely
