  Q: How to Remove the Vapor Canister in an Evaporative Emission Control System on Toyota Prius?

  A:

  The first step to remove the Evaporative Emission Control Canister requires venting all fuel system pressure. Begin by removing the rear No. 2 floor board, then proceed to take off the rear deck floor box followed by the removal of the rear No. 3 floor board. Before installing the negative battery cable breaking, wait a minimum of 90 seconds to avoid Air Bag system activation. The service requires removal of lower center instrument panel finish panel together with the rear seat cushion assembly and rear floor service hole cover and front floor panel brace. Detach the front Exhaust Pipe using a clip remover and fold back the front floor carpet then disconnect the heated oxygen sensor connector before removing its grommet with a pair of pliers followed by purging the 2 bolts and 2 compression springs. You must first disconnect and remove the gasket from the front exhaust pipe then unfasten the two bolts and springs to separate the front exhaust pipe from its mount points with exhaust pipe supports and gasket on the exhaust manifold. The next procedure requires fuel tank sub-assembly removal. The last procedure requires workers to disconnect the pressure switching valve connector and remove the clamp and wire harness clamp followed by disconnecting the 2 canister hoses from fuel tank retainer and fuel tank to canister tube and disconnecting the No. 1 canister outlet hose from the fuel tank before workers remove the bolt and 2 nuts that let them take out the canister.

  Q: How to install a Vapor Canister with a pump module on Toyota Prius?

  A:

  Installing the trap canister with pump module requires connecting the fuel tank vent hose by pushing its connector onto the pipe until it clicks into place after ensuring the area surrounding the connection remains scratch-free and foreign object-free. When you verify a secure connection exists you should place a new fuel gasket before inserting the trap canister and pump module unit into the fuel tank while protecting the gasket from drops. Secure both the trap canister with pump module and fuel tank wire ground terminal using 2 bolts that need a torque value of 6.0 Nm (61 kgf-cm, 53 in-lbf). The next step requires attaching the tube of the fuel tank vent hose to the 2 No. 1 fuel tube using grommet clamps before installing the clamp to the fuel tank vent hose and canister hose and connecting the canister pump module connector. Begin by mounting the canister hose to the 2 No. 1 fuel tube using grommet clamps, then join the tube of the fuel tank to the canister tube and attach the fuel tank main tube clamps to their independent locations. Inspection of fuel and exhaust gas leaks must happen after you install the fuel tank sub-assembly and front Exhaust Pipe and connect the cable to the negative battery terminal. The installation sequence should begin with placing the front floor panel brace and moving through the installation of the rear floor service hole cover and rear seat cushion assembly and lower center instrument panel finish panel and ends with the rear No. 3 floor board and rear deck floor box and rear No. 2 floor board. Perform initialization after disconnecting and reconnecting the cable starting from the negative (-) battery terminal because some systems need it.
