SPECIAL NOTES FOR MULTIPOINT INJECTION
90-TRACK« EMS 31-32 » computer controlling injec-
tion and ignition.
Use of the diagnostic tool.
Multipoint injection operating in sequential mode wi-
thout a cylinder marking sensor or camshaft position
sensor. This means that phasing is carried out by
software using the TDC sensor.
Idle speed corrected according to:
- air conditioning,
- electrical consumers in operation.
Fuel vapour absorber bleed solenoid valve controlled
by the opening cyclic ratio (OCR) according to engine
speed and operating conditions.
Use (on some models) of two oxygen sensors positio-
ned upstream and downstream of the catalytic conver-
ter.
Automatic configuration in air conditioning operating
mode by exchange of signals between the computers.
Deconfiguration is impossible (even using the dia-
gnostic tool).
