Accelerator Pedal Position (App) Sensor Assembly Removal And Installation; Accelerator Pedal Position (App) Sensor Assembly Inspection - Suzuki Grand Vitara 2011 Manual

4) Check that accelerator pedal position sensor voltage
varies as the following graph.
If sensor voltage is out of specified value or does not
vary linearly as the following graph, check
accelerator to "Accelerator Pedal Position (APP)

Assembly Removal and Installation
CAUTION
!
• Do not expose accelerator pedal position
(APP) sensor assembly to excessive shock
like a dropping it. If accelerator pedal
position (APP) sensor assembly has been
exposed to excessive shock, it should be
replaced.
• Be careful not to expose sensor section of
accelerator pedal position (APP) sensor
assembly to water.
Removal
1) Disconnect negative cable at battery.
2) Disconnect connector from accelerator pedal
position (APP) sensor assembly.
3) Remove accelerator pedal position (APP) sensor
assembly from its bracket.

Installation
Reverse removal procedure for installation noting the
following.
• Tighten accelerator pedal position (APP) sensor
assembly upper nut (1) first and then lower nuts (2) to
specified torque.
Tightening torque
Accelerator pedal position (APP) sensor assembly
nut (a): 6.0 N·m (0.6 kgf-m, 4.5 lb-ft)
1, (a)
• If APP sensor assembly bracket is removed, tighten
its mounting nuts to specified torque.
Tightening torque
APP sensor assembly bracket nut: 6.0 N·m (0.6
kgf-m, 4.3 lb-ft)
• Connect connector to accelerator pedal position
(APP) sensor assembly securely.
Accelerator Pedal Position (APP) Sensor
Assembly Inspection
Check accelerator pedal position (APP) sensor (main
and sub) output voltage as following steps.
1) For accelerator pedal position (APP) sensor (main),
arrange 3 new 1.5 V batteries (1) in series (check
that total voltage is 4.7 – 5.0 V) and connect its
positive terminal to "Vin 1" terminal (2) and negative
terminal to "Ground 1" terminal (3) of sensor. Then
using voltmeter, connect positive terminal to "Volt 1"
terminal (4) of sensor and negative terminal to
battery.
