Camry Sedan 4-Door L4-132 2164cc 2.2L DOHC (5S-FE) (1995)
Manifold Absolute Pressure (MAP) Sensor: Testing and Inspection
1. INSPECT POWER SOURCE VOLTAGE OF THE MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR.
-
Disconnect the MAP sensor connector.
-
Turn the ignition switch ON.
-
Using a voltmeter measure the voltage between connector terminals VC and E2 of the wiring harness side.
Voltage: 4.75 - 5.25 volts
-
Turn the ignition switch OFF.
-
Reconnect the MAP sensor connector.
2. INSPECT POWER OUTPUT OF MAP SENSOR.
-
Turn the ignition switch ON.
-
Disconnect the vacuum hose on the air intake chamber side.
-
Connect a voltmeter to terminals PIM and E2 of the ECM, and measure the output voltage under ambient atmospheric pressure.
-
Apply vacuum to the MAP sensor in 13.3 kPa (3.94 in Hg) segments to 66.7 kPa (19.69 in Hg).
-
Measure the voltage drop from the above step for each segment.
Applied Vacuum
/ Voltage Drop;
13.3 kPa (3.94 in hg)
/ 0.3 - 0.5 volts
26.7 kPa (7.87 in hg)
/ 0.7 - 0.9 volts
40.0 kPa (11.81 in hg)
/ 1.1 - 1.3 volts
53.5 kPa (15.75 in hg)
/ 1.5 - 1.7 volts
66.7 kPa (19.69 in hg)
/ 1.9 - 2.1 volts
-
If voltage readings do not read OK, replace MAP sensor.
NOTE: For information on testing the MAP sensor circuit, refer to DTC 31 under the "Trouble Code Charts".
