Your symptoms are all related to P2101: (but it won't be the anti-pollution lamp that is lit - it should be the engine management light as there is a difference).

You can find a lot of the equipment codes here on our Wiki - they are in ascending order in sections:

PSA Electrical Wiring Codes

Fault Code: P2101 - Motorised throttle motor control fault: Not characterised

Description of Fault: Detection of excess current; Fault confirmation time: 2 s. The fault will occur when the ignition is switched on and during the engine ECU sleep phase.

Conditions for Fault to clear: Switching on the ignition or during driving, if the fault is no longer detected.

Downgrade Modes whilst Fault is active: (The Engine Management Lamp will be lit)
  • Minimum open position of the motorised throttle housing
  • Deactivation of the adaptation of the air/petrol mixture
  • Deactivation of the taking account of the value for atmospheric pressure
  • Deactivation of the correction of the mass of air drawn in
  • Deactivation of the canister purge function
  • Deactivation of the vehicle cruise control and speed limiter
Symptoms: Lack of power (Minimum open position of the motorised throttle housing).

Suspect Areas:
  • Motorised throttle unit
  • Engine ECU
  • Electrical harness
So the engine ECU has limited engine speed and disabled the functions listed above until the fault is rectified.

As per your PM, here's some wiring info for you:

1320 is your Engine ECU
1261 is the Accelerator Pedal
1262 is the Motorised Throttle
