(1) MAP 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 TBI. Before testing MAP 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 wire) on Samurai and Sidekick, or terminal B1 (Light Green wire) and terminal A25 (Light Green/Blue wire) on Swift TBI.
(2) Output voltage is checked at ECM connector terminal A22 (Gray/Green wire) and terminal A24 (Gray/Yellow wire) on Samurai and Sidekick, or terminal B2 (Light Green/Red wire) and terminal A25 (Light Green/Blue wire) on Swift TBI. Start engine, if possible, and see if output voltage varies.
CAUTION: Damage to MAP sensor will occur if connections are made incorrectly.

(1) MAP 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 TBI. 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 MAP sensor.
