3. Schematic:
Refer to 2.12.7.52 DTC P2122
4. Diagnostic Steps:
Check APP sensor harness connector IP50 terminal voltage of the No.1.
Step 1
Acceleration Pedal Position Sensor IP50
1 2
Yes
Check resistance between APP sensor harness connector IP50 terminal No.5 and a reliable ground.
Step 2
Conditions For Setting The DTC (Control Strategy)
Voltage is below the minimum limit, or short to ground
Voltage is higher than the maximum limit, or short to power
supply

Control System JL4G15-D
(a) Turn the ignition switch to "OFF" position.
(b) Disconnect APP sensor harness connector IP50.
(c) Turn the ignition switch to "ON" position.
(d) Measure voltage between IP50 terminal No.1 and a reliable
ground.
Standard Voltage: 4.8-5.2 V
Standard values?
If the voltage is higher than the Standard
No
Value, the circuit is short to power supply, if
the voltage is lower than the standard value.
