Note:

(1): D-J Method: When the engine load is light like at idling or low speed, the ECU determines the injection quantity by calculating from the throttle vacuum (vacuum sensor output voltage) and engine speed (crankshaft sensor output voltage). This method is called D-J method.

(2): α-N Method: As the engine speed increases, and the engine load turns middle to heavy, the ECU determines the injection quantity by calculating from the throttle opening (throttle sensor output voltage) and the engine speed. This method is called α-N method.

*: This depends on the number of stopped cylinders.

The main throttle sensor is a rotating variable resistor that change output voltage according to throttle operating. The ECU senses this voltage change and determines fuel injection quantity, and ignition timing according to engine rpm, and throttle opening.

Service Code Erasing
When repair has been done, warning indicator light (LED) and warning symbol go off and service code are not displayed. But the service codes stored in memory of the ECU are not erased to preserve ...

Connecting Rod Big End Side Clearance Inspection
Measure connecting rod big end side clearance. Insert a thickness gauge [A] between the big end and either crank web to determine clearance. Connecting Rod Big End Side Clearance Standard: 0.13 0.38 mm (0.0051 0.0150 in.) Service Limit: 0.58 mm (0.023 in.) If the clearance exceeds ...

Tightening Sequence
Generally, when installing a part with several bolts, nuts, or screws, start them all in their holes and tighten them to a snug fit. Then tighten them according to the specified sequence to prevent case warpage or deformation which can lead to malfunction. Conversely when loosening the bolts, n ...

Crankcase Splitting
Remove the engine (see Engine Removal in the Engine Removal/Installation chapter). Set the engine on a clean surface and hold the engine steady while parts are being removed. Remove: Cylinder Head (see Cylinder Head Removal in the Engine Top End chapter) Starter Motor (see Starter M ...
