Roomster 5J 1.2 EPC light

[eamonndelaney]

Morning Folks

we have a 2007 Roomster 5J 1.2 with an EPC light problem.

 

Checked codes and it said throttle body and throttle pedal sensors. I checked the throttle body had it had a 2014 manufacture date. I replaced the MAF valve as one or twice when the EPC came on the brake pedal went hard.

 

I have since replaced the throttle body and the throttle pedal with secondhand parts.

When the throttle pedal was replaced there was a slight change in throttle response possibly due to different spring tension / resistance.

 

EPC light is still coming on.

 

What else can it be?

 

All suggestions greatly appreciated

Brake light switch/bulbs?

The problem went away shortly after the 2014 manufacture throttle body was replaced with a second hand one. Fitted a secondhand throttle pedal as well. Light came on twice since the parts were replaced but had been without issue for over a month. Had checked the bulb and have bought a new brake light switch as this was next to be eliminated.

 

I'd consider it "cured" at this point.
