P2127, P2128 APP SENSOR
DescriptionINFOID:0000000005398574
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensor detects the accelera-
tor position and sends a signal to the ECM.
Accelerator pedal position sensor has two sensors. These sensors
are a kind of potentiometer which transform the accelerator pedal
position into output voltage, and emit the voltage signal to the ECM.
The ECM judges the current opening angle of the accelerator pedal
from these signals and controls the throttle control motor based on
these signals.
Idle position of the accelerator pedal is determined by the ECM
receiving the signal from the accelerator pedal position sensor. The
ECM uses this signal for the engine operation such as fuel cut.

Remarks:
• Specification data are reference values.
• Specification data are output/input values which are
detected or supplied by the ECM at the connector.
*Specification data may not be directly relat ed to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before m onitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not bei ng adjusted to the specification data. this IGN TIMING
monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and
other ignition timing related sensors.
