Specifications

Emissions Control Devices

  • OBDII - Onboard Diagnostic System (codes can be read/erased by a variety of readers, ie Actron)
  • EGR - Exhaust Gas Recirculation
  • HO2S - (4) Oxygen Sensors (2 before exhaust catalyst, 2 after) - note a series 2 1.8l has only 2 o2 sensors 1 pre and 1 post
  • TWC - Three Way Catalyst (2 in exhaust manifold, 1 under car)
  • EVAP - Charcoal Evaporative Purge Canister
  • Ignition Timing: 9 degrees BTDC (can be altered +/- 2 degrees using CONSULT-II handheld diagnostic tester)
  • Knock Sensor - located on engine block; retards timing if pinging/detonation detected.
  • Heated Throttle Body - heated by engine coolant
