Some 2014-2015 Toyota Tundra vehicles equipped with a 3UR-FE supercharged engine may experience a MIL on with DTC P0101 (mass airflow circuit range/performance problem).
Parts:
PTR43-00090.......................TRD air filter
PTR03-34083......................air box top
17701-0S010......................air box bottom
PTR03-34082......................intake tubes
PTR03-34071.....................air flow monitor, cold air intake
PTR03-35090-AE...............TRD intake hardware rep
Replace the air cleaner box (case) and inlet flow accelerator (plastic piece that extends from lower air canister through right side engine room body panel). Remove the air inlet tube. Disconnect the vacuum and ventilation hoses and loosen the two clamps. Remove the air cleaner lid and disconnect the MAF meter connection. Use a clip removal tool to detach the wire harness clamp. Unfasten the four hook clamps. Remove and discard the air cleaner element. Remove the MAF meter from the air cleaner lid. Discard the air cleaner lid but retain the two screws. Install the MAF meter in the supplied air cleaner lid using the OE screws and torque the screws to 15 in-lbf. Remove the air cleaner case
Install the new air cleaner case using the new bolts that are pre-installed. Use a flat blade screwdriver to unclip and discard the air inlet flow accelerator from the air cleaner case. The inlet to the case is inserted into and snaps to the air flow accelerator. Once the two parts are snapped together push the air flow accelerator further through the panel so the bolt holes align. Torque the bolts to 44 in-lbf.
Install the air filter, air box lid and air inlet tube. Place the hose clamps on each end of the air inlet tube but leave the clamps loose for now. Install the Filter Minder by inserting the grommet into the air box top, making sure that the groove in the grommet is lined up with the air box cover surface. Lube the Filter Minder barbed end and push into the grommet. Place the TRD supplied air filter in the air box base. Clip the supplied air box. Position the inlet hose so that it is in a natural position and tighten the hose clamps. Torque the lamps to 35 in-lbf. Connect the vent hose and fuel pressure regulator hose to the air inlet tube. Plug in the MAF sensor and clip the harness to the air box lid. Connect Techstream to the DLC3.
Turn the ignition switch to ON. Clear DTCs (even if no DTCs are stored, perform DTC clear anyway). Turn the ignition switch OFF and wait for at least 30 seconds. Start the engine and warm up until engine temperature reaches 158 degrees or higher. Drive the vehicle at about 50 – 70 mph for five minutes or more. Keep engine load as stable as possible while driving. Confirm that there are no stored DTCs.
