Peugeot 207 ECU - common anti pollution fault

Peugeot 207 anti pollution fault

This Peugeot 207 ECU is a very common failing unit that affects vehicles built between 2007 and 2015 with the standard 1.4 and 1.6 litre engines and also the higher powered VTi and GT CC versions.

We see a lot of these 207 ECUs failing, causing the 'anti pollution fault' message to be displayed, failure of the coolant temperature sensor/gauge, with a constant overheat warning light on the dashboard, this will also cause the coolant fan to run constantly and may cause engine idling problems, also fault codes stored for the thermostat heater control.

 

Another common symptom of ECU failure is MOT emissions failure caused by a non-functioning lambda sensor circuit, if this occurs then you will likely have fault codes stored for the oxygen 02 sensor. We have also seen failure of this ECU to cause engine misfires and sporadic fault codes for various engine sensors.

 

Common Failure symptoms:

  • Anti pollution warning message
  • Overheat light
  • Idle speed fault
  • Cooling fan constantly running
  • Misfire

 

Common fault codes:

  • P0599 – Thermostat heater control circuit – short circuit to positive
  • P0135 – Oxygen sensor heater malfunction – (Bank1, sensor 1)
  • P0031 – Oxygen sensor heater control circuit low – (Bank 1, Sensor 1)
  • P0141 – Oxygen sensor heater circuit malfunction – (Bank 1, Sensor 2)
  • P0958 – Controlled thermostat control – short circuit to earth
  • P0037 – Oxygen 02 sensor heater control circuit low – (Bank 1, Sensor 1)
  • P2237 – Oxygen sensor positive current control circuit
  • P0014 – Exhaust camshaft dephasing fault coherence

 

Affected Vehicles:

  • Peugeot 207 (2007-2015)
