Wiring Diagram - ENGINE CONTROL SYSTEM -878, (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" 922, precaution for Procedure without Cowl Top Cover, how to Detect Fuel Vapor Leakage 930.
Idle Speed Ignition Timing 932, air Fuel Ratio (A/F) Sensor 1 Heater 932, heated Oxygen sensor 2 Heater 933, input signals from sensors and instantly drives actuators.
Same time, it is important that there are no malfunctions such as vacuum leaks, fouled spark plugs, or other malfunctions with engine, it is much more difficult to diagnose an incident that occurs intermittently rather than continuously, caused by poor electric connections or improper wiring, careful checking of suspected circuits may help prevent the replacement good parts.
A visual check only may not find the cause of incidents, test with CONSULT-III (or GST) or a circuit tester connected should, before undertaking actual checks, take a few minutes talk with.
