So i was driving home, first time in the rain.

I wasn't going fast, car was warm . .had driven 1 km in rain. ..

You go along the road there is a bout a 120 degree left hand turn up a moderate hill with a speed bump. I had lights and a/c on as i went over the bump i noticed the car would still pull with the throttle not pushed i checked this a few times by pushing on the throttle and same thing . .revs would drop to 1500 then go up to 2000. .the throttle became unresponsive and a few hundred meters later the warning came on.

The codes . .

p1602 - throttle unit internal fault
p2135 - throttle/pedal position sensor/switch a/b voltage correlation
p2125 - throttle/pedal position sensor/switch e circuit
p2015 - intake manf runner position sensor/switch circuit range/performance bank 1

I cleared the codes restarted the car a few minutes later and it was fine. Went for a drive on wet grass trying to provoke spin and seemed to work fine.

Do these codes seem to be of things that can fail, because if they can i need to make a plan.

Any comments welcome.
