EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM REMOVAL/INSTALLATION [13B-MSP]

  1. Remove the rear differential. (See «REAR DIFFERENTIAL REMOVAL/INSTALLATION»(ref-367659-S32650357742010072700000) .)
  2. Remove in the order indicated in the figure.
  3. Install in the reverse order of removal.

Evaporative Chamber Installation Note

  1. Install the evaporative chamber to the hose.
  2. Insert the evaporative chamber into crossmember No. 5.

EVAP System Leak Detection Pump Installation Note

  1. Install the bracket on the EVAP system leak detection pump.
  2. Install the connector A.
  3. Install the connector B.
  4. Install the clip.

Removal

CAUTIONThe quick release connector may be damaged if the release tab is bent excessively. Do not expand the release tab over the stopper.

Note. The fuel hose can be removed by pushing it to the pipe side to release the lock.

  1. Rotate the release tab on the quick release connector to the stopper position.
  2. Pull out the quick release connector straight from the port and disconnect it.
  3. Cover the disconnected quick release connector and port with vinyl sheeting or a similar material to prevent it from scratches or dirt.

Installation

Note. If the quick release connector O-ring is damaged or has slipped, replace the quick release connector. A checker tab is integrated with the quick release connector for new fuel hoses and evaporative hoses. Remove the checker tab from the quick release connector after the connector is completely engaged with the fuel pipe.

  1. Inspect the fuel hose and fuel pipe sealing surface for damage and deformation. If there is any malfunction, replace it with a new one.
  2. Apply a small amount of clean engine oil to the sealing surface of the fuel pipe.
  3. Reconnect the fuel hose straight to the fuel pipe until a click is heard. NOTE: If the quick release connector dose not move at all, disconnect it, verify that the O-ring is not damaged or has not slipped, and then reconnect the quick release connector.
  4. Lightly pull and push the quick release connector a few times by hand, and then verify that it can move 2.0-3.0 mm {0.08-0.12 in} and is connected securely.

SECONDARY AIR INJECTION (AIR) CONTROL VALVE REMOVAL/INSTALLATION [13B-MSP]

  1. Remove in the order indicated in the figure.
  2. Install in the reverse order of removal.

SECONDARY AIR INJECTION (AIR) SOLENOID VALVE REMOVAL/INSTALLATION [13B-MSP]

  1. Remove the extension manifold (upper.) (See «INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [13B-MSP]»(ref-367618-S14848159782010072700000) .)
  2. Disconnect the air solenoid valve connector.
  3. Disconnect the vacuum hose from the air solenoid valve.
  4. Remove the air solenoid valve.
  5. Install in the reverse order of removal.

SECONDARY AIR INJECTION (AIR) PUMP REMOVAL/INSTALLATION [13B-MSP]

  1. Remove in the order indicated in the figure.
  2. Install in the reverse order of removal.

Scheme 25

Scheme 25: Using M-MDS
Scheme 25: Using M-MDS
  1. Remove the air hose between the AIR pump and AIR control valve at the AIR control valve side.
  2. Install the SST on the AIR control side using tape to prevent air leakage.
  3. Start the engine, turn all electrical loads off, and idle the engine after completely warming it up.
  4. Connect the M-MDS to the DLC-2.
  5. Turn the PID "AIP RLY" from off to on position using the simulation function. (See «ONBOARD DIAGNOSTIC TEST [13B-MSP]»(ref-367617-S28888613132010072700000) .) CAUTION: When connecting the secondary air injection pump relay to the body ground, short the specified terminal, because shorting the wrong terminal may cause malfunctions. Do not operate the secondary air injection pump for more than 1 min. to avoid damaging the pump. Stop the engine and wait for 1 h or more after energization of the secondary air injection pump to allow it to cool down before operating it again.
  6. Verify that the discharging pressure of the AIR pump is within the specification. If not within the specification, inspect the following: PCM terminal 1G and AIR pump relay terminal A AIR pump relay If it is within the specification, inspect the continuity for the AIR pump.

Discharging pressure

6-12 kPa {0.07-0.12 kgf/cm 2 , 0.9-1.7 psi} [15-35°C {59-95°F}]

Scheme 26: Without using M-MDS
Scheme 26: Without using M-MDS
  1. Remove the air hose between the AIR pump and AIR control valve at the AIR control valve side.
  2. Install the SST on the AIR control side using tape to prevent air leakage.
  3. Position the PCM out of the way with the connects still connected. (See «PCM REMOVAL/INSTALLATION [13B-MSP]»(ref-367617-S28888613132010072700000) .)
  4. Start the engine, turn all electrical loads off, and idle the engine after completely warming it up.
  5. Connect the AIR pump relay terminal A to the ground, and operate the AIR pump. CAUTION: When connecting the secondary air injection pump relay to the body ground, short the specified terminal, because shorting the wrong terminal may cause malfunctions. Do not operate the secondary air injection pump for more than 1 min. to avoid damaging the pump. Stop the engine and wait for 1 h or more after energization of the secondary air injection pump to allow it to cool down before operating it again.
  6. Verify that the discharging pressure of the AIR pump is within the specification.
  1. If not within the specification, inspect the following
  1. AIR pump relay
  1. If it is within the specification, inspect the continuity for the AIR pump.

Discharging pressure

6-12 kPa {0.07-0.12 kgf/cm 2 , 0.9-1.7 psi} [15-35°C {59-95°F}]
