Signs You Need a Replacement

If your equipment is showing any of these symptoms, the throttle body may be the cause:

• Surging or fluctuating idle speed — The throttle plate or motor is sticking, causing the ECU to hunt for the correct idle position. This is the most common early symptom.
• Reduced throttle response — A dirty or worn throttle body doesn’t open smoothly. You’ll notice a dead spot or hesitation when you press the pedal.
• Check engine light with P0121 or P1545 — These codes indicate a throttle position correlation error. If cleaning doesn’t clear them, the throttle body needs replacement.
• Limp mode activation — The ECU limits engine speed when it can’t trust the throttle position signal. This safety mode prevents damage but limits operation.
• High idle that won’t come down — Carbon buildup holds the throttle plate slightly open. The ECU compensates by raising fuel trim, which may trigger adaptive mixture codes.
• Stalling at low RPM — When the throttle body can’t maintain a stable idle, the engine may stall at stoplights or when shifting from drive to reverse.

Post-Installation Adaptation

After installing the new throttle body, perform a throttle adaptation so the ECU learns the new zero and full-throttle positions. With VCDS or equivalent: go to Engine, Basic Settings, channel 060 or 098 (varies by ECU), and follow the on-screen prompts. Without a diagnostic tool, use the manual method: turn the key ON (engine off) for 60 seconds, then OFF for 10 seconds. Start the engine and let it idle for 3 minutes without touching the accelerator. Do not rev the engine during this process.

Frequently Asked Questions

Which Honda models does this part fit?
Refer to the Vehicle Compatibility table above for the full list of Honda models. Each listing includes the body type, engine, and production years. Match your vehicle’s engine code (stamped on the engine block) against the listed codes to confirm.

Can I cross-reference 164005J6A01 with 672020?
Yes. Both 164005J6A01 and 672020 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions.

I have a 3.0L engine – which version do I need?
This part covers 3.0L applications. To narrow down the exact fit, check your vehicle’s model year and engine code. The same displacement can have multiple engine variants with different fuel systems or emissions equipment.

My vehicle is a 2016 model – is it covered?
The compatibility range for this part includes 2016-2023. The 2016 model year falls within this range, but verify the engine code and body type match. Mid-year production changes sometimes mean two vehicles from the same model year use different parts.
