LESSON 3: POWERTRAIN
Accelerator Pedal Position Sensor (APPS) Check
The Accelerator Pedal Position Sensor (APPS) check watches for certain failure modes and stores the appropriate
DTC.
•
The following DTCs apply to the accelerator pedal position sensors:
DTC Description
P2122 APPS 1 circuit Low Input (ETC light, Selects APPS 2, non-MIL)
P2123 APPS 1 circuit High Output (ETC light, selects APPS 2, non-MIL)
P2121 APPS 1 range/performance (ETC light, selects APPS 2, non-MIL)
P2138 APPS 1/APPS 2 voltage correlation (ETC light, or message center text, non-MIL)
P2127 APPS 2 Low Input (ETC light, selects APPS 1, non-MIL)
P2128 APPS 2 High Input (ETC light, selects APPS 1, non-MIL)
P2126 APPS 2 range/performance (ETC light, selects APPS 1, non-MIL)
P2140 APPS 2/APPS 3 voltage correlation (ETC light, selects APPS 1, non-MIL)
P2132 APPS 3 Low Input (ETC light, Selects APPS 1, non-MIL)
P2133 APPS 3 High Output (ETC light, Selects APPS 1, non-MIL)
P2131 APPS 3 range/performance (ETC light, Selects APPS 1, non-MIL)
P2139 APPS 1/APPS 3 voltage correlation (ETC light, selects APPS 1, non-MIL)
•
These codes are continuously monitored and require less than one second to register a malfunction.
•
Circuits are monitored and DTCs are set if voltages are above or below voltage values specified in the PCED
manual.
