STEP 1. Using scan tool (M.U.T.-IIISE), read the diagnostic trouble code (DTC).
caution | To prevent damage to scan tool (M.U.T.-IIISE), always turn off the power supply mode of the electric motor switch before connecting or disconnecting scan tool (M.U.T.-IIISE). |
(1) Connect scan tool (M.U.T.-IIISE). Refer to HOW TO CONNECT THE SCAN TOOL (M.U.T.-IIISE) . (2) Turn on the power supply mode of the electric motor switch.
(3) Read the DTC.
(4) Turn off the power supply mode of the electric motor switch.
Is the diagnostic trouble code other than P1469 set?
Refer to Diagnostic Trouble Code Chart . Go to Step 2.
STEP 2. Using scan tool (M.U.T.-IIISE), check data list item 212: Canister Pressure Sensor.
(1) Turn on the power supply mode of the electric motor switch.
(2) Set scan tool (M.U.T.-IIISE) to the data reading mode for item 212, Canister Pressure Sensor.- When altitude is 0 m (0 foot), 101 kPa (29.8 in.Hg).
- When altitude is 600 m (1,969 feet), 95 kPa (28.1 in.Hg).
- When altitude is 1,200 m (3,937 feet), 88 kPa (26.0 in.Hg).
- When altitude is 1,800 m (5,906 feet), 81 kPa (23.9 in.Hg).
(3) Turn off the power supply mode of the electric motor switch.
Is the sensor operating properly?
Go to Step 5. Go to Step 3.
STEP 3. Measure the sensor supply voltage at evaporative leak check module harness side connector.
STEP 4. Check of short to ground and open circuit in EVSS line between evaporative leak check module connector and ECM connector.
STEP 5. Using scan tool (M.U.T.-IIISE), check data list item 8: Manifold Absolute Pressure Sensor.
(1) Turn on the power supply mode of the electric motor switch.
(2) Set scan tool (M.U.T.-IIISE) to the data reading mode for item 8, Manifold Absolute Pressure Sensor.- When altitude is 0 m (0 foot), 101 kPa (29.8 in.Hg).
- When altitude is 600 m (1,969 feet), 95 kPa (28.1 in.Hg).
- When altitude is 1,200 m (3,937 feet), 88 kPa (26.0 in.Hg).
- When altitude is 1,800 m (5,906 feet), 81 kPa (23.9 in.Hg).
(3) Set the vehicle to the continuous idling mode, and warm up the engine.- The standard value should be 28.3 - 41.7 kPa (8.36 - 12.31 in.Hg).
- When the engine is suddenly revved, manifold absolute pressure varies.
(4) Turn off the power supply mode of the electric motor switch.
Is the sensor operating properly?
Go to Step 6. Refer to DTC P0106 - Manifold Absolute Pressure Circuit Range/Performance Problem , DTC P0107 - Manifold Absolute Pressure Circuit Low Input , DTC P0108 - Manifold Absolute Pressure Circuit High Input . Then go to Step 7.
STEP 6. Using scan tool (M.U.T.-IIISE), check the evaporative emission system monitor test
STEP 7. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 4 . (2) Check the diagnostic trouble code (DTC).
Is DTC P1469 set?
Retry the troubleshooting. The inspection is complete.
