Stp Sensor Adjustment - Suzuki GSX1400 Service Manual

4-62 FI SYSTEM
• Set the No.3 and No.4 STV's to the same opening by turning
the balance screw 1. Then, set the No.1/No.2 valves and No.3/
No.4 valves to the same opening by turning the balance screw
2.
• Install the TP sensor to the No.1 throttle body and STP sensor
to the No.4 throttle body respectively.

NOTE:
* Apply grease "A" to the shaft end A if necessary.
* STP sensor and TP sensor resemble each other very closely
in external appearance. Make sure to check the color of cou-
pler before connecting.

STP SENSOR ADJUSTMENT

If the STP sensor adjustment is necessary, measure the sensor
resistance and adjust the STP sensor positioning as follows:
• Disconnect the STP sensor coupler.
• Set the ST valve to fully close position by finger and measure
the resistance between yellow and black wires.
STP sensor setting resistance
ST valve is fully closed: Approx. 0.8 kΩ Ω Ω Ω Ω
09900-25008: Multi circuit tester
Tester knob indication: Resistance (Ω Ω Ω Ω Ω )
• Loosen the STP sensor mounting screws.
• Adjust the STP sensor until resistance is within specification
and tighten the STP sensor mounting screws.

STP sensor mounting screw: 3.5 N . m
If the measured resistance is not within specification, adjust the
STV adjuster B as follows:
• Under above condition, turn in or out the STV adjuster B until
the resistance becomes specified value.
If the measured resistance is not obtain, replace the STP sen-
sor with a new one, and adjust the STP sensor positioning again.
NOTE:
To adjust the TP sensor, install the throttle body assembly to the
engine and after warming up engine. (
