My Ford shows up the following diagnosis:

P2135 Throttle position sensors A and B; plausibility error

            - Error

            - Present

P0223 Throttle/Pedal Position Sensor/Switch B Circuit intermittent

            - Circuit high input

            - Present

If anyone has come across these faults before and could tell me the most likely way of fixing them I really would be so grateful.

Look like you need a new TPS (Throttle Position Sensor) it seems to be not communicating properly with the ecu. This will cause problems as it won't know how hard you are pressing the accelerator. 

What causes the 2135 code?

• Faulty PCM
• Faulty throttle position sensor(s)
• Faulty accelerator position sensor
• Disruption in the throttle position sensor circuit such as an open, corrosion, short, damaged wiring or broken electrical connections
• Disruption in the accelerator pedal position sensor circuit such as an open, corrosion, poor electrical connection, short, damaged wiring or broken electrical connections

What are the symptoms of the P2135 code?

• Surge or even possibly a hesitation when accelerating
• Revving of the engine when gas pedal is not pressed
• RPM’s are higher than usual
• Check Engine Light illumination
• Vehicle may stall out

Thank you very much for your reply, I really do appreciate it.  I will now try and get the Throttle Position Sensor and the electrical connections checked.  Now you mention it I think the fault may well be due to a faulty connection since the last time the fault occurred was after it had been raining. Thank you again for going to the trouble of answering my query.
