October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Engine Load Sensor

Engine load is determined by vacuum level, and throttle position. On 4 cylinder engines, an idle tracking switch signals the MCU when the throttle is closed. A vacuum switch signals wide open conditions. On 6 and V8 models, 3 vacuum switches are used to signal cruise, deceleration, and wide-open-throttle conditions. No throttle switch is used on these models.
