MPV ES V6-2.5L DOHC (2001)
EGR Boost Sensor: Testing and Inspection
NOTE: Perform the following test only when directed.
Voltage Inspection
Using the SST (104 pin breakout box)
1. Turn the ignition switch to LOCK.
2. Disconnect the PCM connector.
3. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
4. Tighten the connector attaching bolt.
Tightening torque
3.0 - 5.4 N.m {30 - 56 kgf.cm, 27 - 48 in.lbf}
5. Turn the ignition switch to ON.
6. Disconnect the vacuum hose between the EGR boost sensor and the EGR boost sensor solenoid valve.
7. Verity that the PCM 34 terminal voltage is within the specification.
NOTE
-
The output voltage varies with the following condition.
-
Input voltage 4.5 - 5.5 V
-
Outside temperature 10 - 50 °C {50 - 122 °F}
-
Sea level -200 - 3,000 m {-656 - 9,840 ft}
Specification
Measurement voltage: 2.3 - 4.7 V
CAUTION: Do not apply vacuum out of specification. Doing so will damage the EGR boost sensor.
8. Apply vacuum of -26.6 kPa {-200 mmHg, -7.85 inHg} to the EGR boost sensor and verity that PCM 34 terminal voltage varies from Step 7 as
specified.
-
If not as specified, perform the "Circuit Open/Short Inspection".
Specification
Voltage variation: 0.8 - 1.3 V
