Pressure (MDP) Sensor

WARNING: This page is about a different car, the 1996 Suzuki Sidekick. However, it is still accessible from the selected car via links, so may be relevant.

To bench test pressure sensor, see appropriate MAP SENSOR OUTPUT VOLTAGE (OFF-VEHICLE) table. If voltage is not within specification, replace MAP sensor.
If scan tool reading is not within specification, see DTC P1408 (Sidekick) in appropriate BASIC TESTING - 1.6L article. Since many computer-controlled and monitored components set a Diagnostic Trouble Code (DTC) if they malfunction, also perform procedures in TESTS W/CODES - 1.6L article.

CAUTION: Damage to MAP sensor will occur if connections are made incorrectly.

MAP SENSOR OUTPUT VOLTAGE (OFF-VEHICLE) - SIDEKICK

Vacuum (In. Hg)

⁽¹⁾⁽²⁾ Output Voltage

2.4-4.4

2.1-4.1

1.9-3.9

1.6-3.6

1.3-3.3

⁽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. Negative lead of batteries is connected to "Ground" terminal. Check output voltage between "Vout" and "Ground" terminals.

⁽²⁾	Voltage should reduce when up to 15 in. Hg of vacuum is applied to MAP sensor.
