This OEM-grade 60mm electronic throttle body assembly is a direct throttle body replacement for Honda Accord, Civic Si, CR-V, Element, and Acura CSX with 2.0L/2.4L K-Series naturally aspirated engines (K20Z2, K24A8, K24Z1, K24Z4). Whether you need a full throttle body replacement after throttle body actuator failure, a throttle body tps sensor fault (P0120, P0121, P2100, P2119, P2135), or a scheduled throttle body service, this unit is engineered to Honda OEM specifications for precise throttle response and long-term reliability. The die-cast aluminum housing and Viton throttle body gasket seals ensure airtight fitment with no wiring modification required. Please verify your OE number before ordering.

A throttle body relearn procedure is required after installation to recalibrate the throttle body position sensor baseline — this is standard throttle body service practice for Honda K-Series platforms. Disconnect battery for 5–10 minutes before installation. Install a new throttle body gasket (most aftermarket units include one). Turn ignition ON (do not start) for 10 seconds, then OFF for 10 seconds. Start engine and idle for 5 minutes without touching the accelerator. If issues persist, use Honda HDS scanner to perform “Throttle Body Learn” or “Idle Relearn”. Non-professionals should not attempt installation.
