Drove home ok, next time I started the engine there is now no throttle response, just idles but will some time creep up to 2000 revs. I have checked the faults there were 9 recorded. I have cleared them and 3 throttle faults do come back. P0120,P0220,P0221. I have 5volts on pins 2 and 5. Pins 1and 4 read .40 volts off throttle and 3.20 volts full throttle. do these look ok. before I delve any deeper
