Description
The accelerator position sensor is installed on the upper end of the accelerator pedal assembly. The sensor
detects the accelerator position and sends a signal to the ECM. The ECM uses the signal to determine the
amount of fuel to be injected.
The accelerator position switch detects Off-accelerator switch signal and Full-accelerator switch signal (A/T
models only) and send these signals to the ECM. The ECM will then determine engine idle conditions. These
signals are also used for diagnosing the accelerator position sensor.
