DTC P0225: Pedal Position Sensor 1 Circuit
NOTE:
• Priority when dealing with a number of DTCs:
If DTC P0225 and DTC P0641 are detected, deal with DTC P0641 Sensor Reference Voltage 1 first.
• If DTC P0225 is detected, engine speed maintained above 1000 rpm and engine performance reduced to 75%.
• If DTC P0225 and DTC P2120 are detected, engine speed fixed at 1300 rpm.
Wiring Diagram
For wiring circuit and connector number, refer to “K9K Engine (Type 5)” in A-4 Engine Control System Circuit Diagram .
Detecting Condition
NOTE:
Generic scan tool displays status with * mark only.
Status displayed on SUZUKI scan tool Detecting condition Indicator / Warning light operation
D1 Incoherence Injection warning light (gravity 1 fault) light up
D2 No signal
D3 Component stuck
*CO 0 Open circuit or short circuit to ground
*CC 1 Short circuit to 12 V
Troubleshooting for D1: Incoherence, D3: Component Stuck
Disconnect the ECM “E17” connector and the APP sensor connector.
Check for insulation between “E17-3” terminal and “E17-21” terminal of ECM connector
Repair if necessary. If DTC P0225 is still detected, replace the APP sensor.
If DTC P0225 is still detected, replace the ECM.
Troubleshooting for CO 0: Open Circuit or Short Circuit to Ground, CC 1: Short Circuit to +12 Volt or D2: No Signal
Check the connection and condition of the APP sensor connector.
Repair if necessary.
Check the connection and condition of the ECM “E17” connector.
Repair if necessary.
Check APP sensor for resistance referring to APP Sensor Inspection:K9K .
Replace the APP sensor necessary.
Check for 5 V on “E97-4” terminal of APP sensor connector.
Check for earth on “E97-5” terminal of APP sensor connector.
Repair if necessary.
Check for insulation, continuity and absence of interference resistance of the connections:
• Between “E97-3” terminal of APP sensor connector and “E17-4” terminal of ECM connector
• Between “E97-4” terminal of APP sensor connector and “E17-3” terminal of ECM connector
• Between “E97-5” terminal of APP sensor connector and “E17-5” terminal of ECM connector
Repair if necessary.
Disconnect the ECM “E17” connector and the APP sensor connector.
Check for insulation between “E17-3” terminal and “E17-21” terminal of ECM connector.
Repair if necessary. If DTC P0225 is still detected, replace the APP sensor.
If DTC P0225 is still detected, replace the ECM.
After Repair
Deal with any faults detected by SUZUKI scan tool.
Clear the DTC.
Carry out a road test followed by another check with the SUZUKI scan tool.
