MPV LX V6-2.5L DOHC (2000)
Fuel Tank Pressure Sensor: Testing and Inspection
Using the SST (NGS Tester)
NOTE: Perform the following test only when directed.
1. Turn the ignition switch to
ON.
2. Disconnect the vacuum hose between the fuel tank pressure sensor and charcoal canister.
CAUTION: Do not apply vacuum out of specification. Doing so will damage the fuel tank pressure sensor.
Specification
3. Apply pressure then vacuum to the fuel tank pressure sensor according to the following procedure.
1. Decrease the applied pressure from
+6.66 kPa {+50 mmHg, +1.97 inHg} to -6.66 kPa {-50 mmHg, -1.97 inHg} and verify that the FTP V
PID decreases accordingly as specified.
-
If not as specified, perform the "Circuit Open/Short Inspection".
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}
Circuit Open/Short Inspection
1. Disconnect the PCM connector.
2. Connect the SST (104 Pin Breakout Box) with the PCM disconnected.
3. Tighten the connector attaching bolt.
Tightening torque
7.9 - 10.7 N.m {80 - 110 kgf.cm, 69.5 - 95.4 in.lbf}
4. Inspect the following wiring harness for open or short (Continuity check).
Open circuit
-
If there is no continuity, the circuit is open. Repair or replace the harness.
