Sensor Operating Range Charts: Notes

NOTE: Unless stated otherwise in test procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.
CAUTION: Blowing compressed air through airflow sensor will damage it.

(1) Pressure sensor output voltage is tested with coupler connected to ECM. ECM is located near glove box on Samurai or upper left corner of instrument panel on Sidekick and Swift SOHC. Before testing pressure sensor output voltage, ensure ECM supply voltage is 4.75-5.25 volts at connector terminal A23 (Gray/Red wire) and terminal A24 (Gray/Yellow) on Samurai and Sidekick or terminal B1 (Light Green wire) and terminal A25 (Light Green/Blue) on Swift SOHC.
(2) Output voltage is checked at ECM connector terminal A22 (Gray/Green wire) and terminal A24 (Gray/Yellow) on Samurai and Sidekick or terminal B2 (Light Green/Red wire) and terminal A25 (Light Green/Blue) on Swift SOHC. Start engine, if possible, and see if output voltage varies.
CAUTION: Damage to pressure sensor will occur if connections are made incorrectly.

(1) Pressure sensor output voltage is tested with three 1.5-volt batteries connected in series (output 4.5-5.0 volts). Positive lead of batteries is connected to VIN terminal on Samurai, Sidekick and Swift SOHC. Negative lead of batteries is connected to ground terminal. Check output voltage between VOUT terminal and ground.
(2) Voltage should reduce when up to 15 in. Hg of vacuum is applied to pressure sensor.

(1) To obtain idle position, apply 19 in. Hg vacuum to throttle opener.
(2) There should be more than 2000 ohms difference between idle and wide open throttle readings.
(3) Throttle position sensor is used only on auto. transaxle, manual transaxle uses a throttle switch.
