Step 2
1) Turn the ignition switch OFF.
2) Remove the air cleaner box. (!Page 51)
3) Connect the STP sensor coupler.
4) Insert the needle pointed probes to the STP sensor coupler.
5) Disconnect the STVA lead wire coupler.
6) Turn the ignition switch ON.
7) Measure the STP sensor output voltage at the coupler
(between + Yellow wire and - B/Br wire) by turning the sec-
ondary throttle valve (close and open) with a finger.
$ STP sensor output voltage
Secondary throttle valve is closed: Approx. 0.6 V
Secondary throttle valve is opened: Approx. 4.5 V
# 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
) Tester knob indication: Voltage (()
Is the voltage OK?
• Y, R, B/Br wire open or shorted to ground, or
poor 4, 5 or B connection.
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
YES
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
• Reset the STP sensor position correctly.
NO
• Replace the STP sensor with a new one.
"C31" (P0705) GP SWITCH CIRCUIT MALFUNCTION
On model K7, the connector terminals to be used for checking
sensors for voltage, resistance or continuity at the ECM terminal
are located as shown in the illustration.
* Refer to the DL650 service manual 4-41 for details.
