Dtc P0225: Accelerator Pedal Position - Suzuki GRAND VITARA 2005 Service Manual

1A-42 Engine General Information and Diagnosis:
Troubleshooting
Check the connections on fuel injector No.4.
Check the ECM connections.
Repair if necessary.
Disconnect fuel injector No.4.
Measure the resistance of fuel injector No.4 between "C07-1" and "C07-2" terminals.
Replace the fuel injector if there is a short circuit (R = 0 Ω) or an open circuit (resistance = infinity).
Otherwise reconnect fuel injector No.1.
Check the following connections for continuity and make sure there is no interference resistance:
• Between "C07-2" wire of fuel injector No.4 connector and "C85-28" terminal of ECM connector
• Between "C07-1" wire of fuel injector No.4 connector and "C85-31" terminal of ECM connector
If the fault is still present: apply Test 8 of Fault Finding-Tests referring to "Test 8: Injector malfunction: ".
If the fault is still present, substitute a known-good ECM and recheck.
DTC P0225: Accelerator Pedal Position (APP) Sensor Assembly / Switch "C" Circuit Malfunction
CAUTION
!
• This fault may appear if the wiring harness has been damaged.Follow the procedure described in
"Electrical Circuit Inspection Procedure: in Section 00 in related manual".
• This check enables the condition and the conformity of the engine wiring harness to be checked.
NOTE
• Conditions for applying the fault finding procedure to stored faults:
– The fault is declared present after a series of full load/no load actions on the accelerator pedal.
• Turbocharging, passenger compartment heating resistor activation and cruise control/ speed limiter
are not authorised.
If CO.0, CC.1, 1.DEF is present the Injection warning light (gravity 1 warning light) is lit.
• The engine speed is fixed at 1400 rpm if there is a fault on main and sub of the accelerator pedal
position (APP) sensor and the engine torque is limited.
• Use service wire for all operations on the controller connectors.
• Priorities when dealing with a number of faults:
– Deal with fault "DTC P0641: Sensor Reference Voltage "A" Circuit / Open Malfunction: " first if it is
present or stored.
