Throttle Position Sensor....

[tmp]

Hi all, I a newby to this forum, so please bear with!

My 2014 MK7 Golf GT has developed a very intermittened fault, started last week when the EPC light came and it went into limp mode, went away for a little while then came back with the addition of the engine (cat fault) light.  The codes I have from the OBD2 are as follows:

P0122 [0x0122]
Throttle position (TP) switch A/accelerator pedal position (APP) switch A - low input
Throttle Position (TP) Sensor Circuit Low Voltage
Status: Confirmed
----------------------------
P0222 [0x0222]
Throttle position (TP) sensor B/accelerator pedal position (APP) sensor B - low input
APP Sensor 2 Circuit Low Voltage
Status: Confirmed

So seems to be a fault with the TPS.

I had a minor accident and got the car back about a month ago, wasn't serious and was repaired, but there was damage to the bumper, bonnet, ACC camera etc etc.  I know its quite tight with probably only 3" or so of clearance to the throttle body assy.  I didn't see if the damage was enough to impact the throttle body and maybe caused a latent failure thats just now shown up.  Thoughts on this would be much apprecited??

Also, I've been looking, without success, can the TP sensor for a mk7 golf be bought on its own or do I have to buy the whole throttle body assy?

Thanks for any comments.

I would start by examining the wiring from the sensor and particularly if it routes through the front end area
Potential of damage to the wiring may cause the faults as its voltage related?
