This procedure covers removal and replacement of the throttle body on a 2012-2017 Toyota Camry with the 2.5L I4 engine, including disconnection of sensors and air intake components.

Warnings

Tools required

Parts

• Throttle body gasket × 1 — Use OEM specification
• Throttle body assembly × 1 — 22030-0V010 (if replacing)

Fluids

• Toyota Super Long Life Coolant (Pink) — 0.5 qt

Preparation

1. Ensure engine is completely cool to the touch
2. Park vehicle on level surface and engage parking brake
3. Disconnect negative battery terminal and wait 3 minutes for airbag system discharge
4. Place drain pan or towels under throttle body area to catch any coolant spillage

Procedure

1. 1

   Remove engine cover
   Grasp the engine cover firmly and pull upward to disengage the rubber grommets from their mounting posts. Set cover aside.
2. 2

   Disconnect air intake hose
   Loosen the air intake hose clamp at the throttle body using a flathead screwdriver or 8mm socket. Pull the intake hose off the throttle body inlet and move it aside for access.
   Torque spec

   Air Intake Hose Clamps3 Nm (2 lb-ft)
3. 3

   Disconnect throttle body electrical connector
   Press down on the locking tab of the throttle position sensor/throttle control motor connector and pull it straight off the throttle body. Do not pull on the wiring harness.
4. 4

   Disconnect coolant bypass hoses
   Using pliers or a flathead screwdriver, release the hose clamps on both coolant bypass hoses connected to the throttle body. Twist and pull the hoses off the throttle body nipples. Some coolant will drain from these hoses; catch in a drain pan.
   ⚠Expect approximately 4-6 ounces of coolant to drain from the bypass hoses. Have towels or drain pan ready.
5. 5

   Remove throttle body mounting bolts
   Using a 10mm socket, remove the four throttle body mounting bolts securing the throttle body to the intake manifold. Keep bolts organized for reinstallation.
   Torque spec

   Throttle Body Bolts10 Nm (7 lb-ft)
6. 6

   Remove throttle body assembly
   Carefully pull the throttle body away from the intake manifold. Remove and discard the old gasket from the mating surface. Inspect the intake manifold opening for debris or damage.
7. 7

   Clean mating surfaces
   Using a plastic scraper and clean shop towels, thoroughly clean both the intake manifold mating surface and the throttle body mating surface. Ensure no gasket material or debris remains. Do not allow debris to fall into the intake manifold opening.
   ⚠Cover the intake manifold opening with a clean towel while cleaning to prevent debris entry.
8. 8

   Install new gasket and throttle body
   Position the new throttle body gasket on the intake manifold, aligning all mounting holes. Carefully position the throttle body assembly onto the gasket, ensuring proper alignment with all four mounting holes.
9. 9

   Install and torque mounting bolts
   Install all four throttle body mounting bolts hand-tight. Using a torque wrench, tighten the bolts in a criss-cross pattern to the specified torque of 14.0 Nm (10 lb-ft) to ensure even gasket compression.
   Torque spec

   Throttle Body Bolts10 Nm (7 lb-ft)
10. 10

    Reconnect coolant bypass hoses
    Reconnect both coolant bypass hoses to the throttle body nipples. Ensure hoses are fully seated, then secure with hose clamps tightened to 4.0 Nm (3.0 lb-ft).
11. 11

    Reconnect electrical connector and air intake
    Reconnect the throttle body electrical connector until it clicks into place. Slide the air intake hose onto the throttle body inlet and tighten the hose clamp to 4.0 Nm (3.0 lb-ft).
    Torque spec

    Air Intake Hose Clamps3 Nm (2 lb-ft)
12. 12

    Refill coolant and check level
    Check coolant level in the reservoir and add Toyota Super Long Life Coolant as needed to bring to the FULL mark. Reconnect the negative battery terminal.

Reassembly

1. Reinstall engine cover by aligning grommets with mounting posts and pressing down firmly
2. Ensure all electrical connectors are fully seated with audible clicks
3. Verify all hose clamps are properly tightened and hoses are fully seated

Verification

• Start the engine and allow it to idle for 2-3 minutes while monitoring for coolant leaks at the throttle body bypass hoses
• Check for air leaks around the throttle body gasket by listening for hissing sounds at idle
• Verify smooth throttle response by gently pressing and releasing the accelerator pedal
• Check coolant level after engine reaches operating temperature and top off if necessary
• Verify no check engine light illumination; throttle body should perform self-learning during initial drive cycle
• Test drive the vehicle to confirm normal acceleration and idle quality
