Vauxhall Vectra/Zafira/Astra 1.8 ECU 1995 - 2007

Vauxhall engine ECU malfunction

ECU System:  Siemens Simtec 70 & 71

ECU Location:  Bolted to the side of the engine block

ECU rebuild time: 2-3 working days

 

The Siemens 1.8 ECU fitted to all late Vauxhall's is one of the most common ECU failures ever.

Symptoms normally start with the engine management light coming on followed by a hesitation. When the fault codes are read they normally blame the Air Mass Meter and air temp sensor but this is a false code as the problem is always inside the ECU, the Simtec71 system causes a misfire on one cylinder when it fails. We can rebuild customers own units so that there is no need for expensive reprogramming when the ECU is refitted.

 

Common Failure symptoms:

  • Misfire
  • Cutting out when warm/hot
  • Poor idle
  • Engine management light (EML)
  • No start

 

Common fault codes:

  • P0100 – Mass or volume air flow sensor circuit high
  • P0505 – Idle air control voltage high
  • P0351 – Ignition malfunction cylinder 1
  • P0354 – Ignition coil 4 control circuit
  • P0201 – Injector valve 1 open circuit
  • P0335 – Crankshaft sensor open circuit
  • P0220 - Throttle/Pedal Position Sensor/Switch B Circuit Malfunction
  • P0120 - Throttle Pedal Position Sensor/Switch A Circuit Malfunction
  • P1550 - Throttle in emergency mode setting
  • P1120 – APP sensor 1 low input
  • P1122 – APP sensor 2 low input

  • Vauxhall Corsa 2000 - 2007
