a) Disconnect the sensor connector.
b) Turn on the ignition.
c) Using a voltmeter, measure the voltage between the terminals of the sensor connector on the wiring harness side "VC" and "E2".
- Nominal voltage - 4.5-5.5 V
d) Reconnect the sensor connector.
2. Check the output signal of the absolute pressure sensor in the intake manifold.
a) Turn on the ignition.
b) Disconnect the vacuum hose from the intake manifold.
c) Connect a voltmeter to the "PIM" and "E2" terminals of the electronic control unit connector and measure the output signal voltage at atmospheric pressure.
d) Apply vacuum to the sensor in stages within the range from 13.3 kPa to 66.7 kPa.
d) Measure the decrease in voltage for each vacuum value.
