Parts for your 2016 Honda Accord-Throttle position sensors

2016 Honda Accord Throttle Position Sensor (TPS)

Technical sources confirm the 2016 Honda Accord absolutely uses a throttle position sensor. The factory 2013–2017 Accord Service Manual (Helm/ESM) and Honda Service News on Electronic Throttle Control describe an electronic throttle body with dual built‑in TPS tracks that the PCM monitors for correlation. Industry databases such as ALLDATA and Mitchell 1 list related DTCs (P0121/P0122/P0123, P0222/P0223, P2135) for this model, and specify the TPS is integral to the throttle body and not serviced separately. So yes—on a 2016 Accord, the TPS is relevant, always in play, and part of the throttle body assembly.

On this Accord, the TPS tells the engine computer exactly how far the throttle plate is open. Paired with accelerator pedal position sensors and the throttle actuator motor, it makes up the drive‑by‑wire system. That lets the car blend driver intent with traction, idle, and emissions strategies for smooth take‑off, tidy shifts, and consistent fuel economy over the kilometres.

When it’s healthy, no one notices it. When it’s not, the dash light pops on and the drive can feel a bit crook—think hesitant acceleration, odd surging, or a high/low idle. The PCM will usually log a code and may limit throttle as a safety back‑up if the two TPS signals don’t agree.

Servicing a 2016 Honda Accord throttle-position-sensor is really about looking after the throttle body it’s built into. The sensor itself isn’t adjustable and isn’t sold on its own. If diagnostics point to a failed TPS, the fix is a complete throttle body replacement with a new gasket. After that, perform an idle learn/throttle position relearn (Honda HDS or an approved scan tool is ideal). Without a tool, a basic learn can happen by warming the engine, turning all loads off, and letting it idle for several minutes until the fans cycle—then a short, mixed drive.

• Helpful maintenance: clean the throttle bore and plate gently with sensor‑safe cleaner during scheduled services.
• Watch for symptoms: MIL on, limp mode, uneven idle, poor throttle response.
• Don’t back‑probe or force the plate—damage can cook the tracks or motor.
• Battery disconnects can trigger idle relearn needs, plan for it after work.

Look after the throttle body, and the TPS will happily keep doing its thing, keeping that 2016 Accord feeling crisp and reliable for the long haul across Aussie and Kiwi roads.

FAQs

Does the 2016 Accord have a separate, replaceable TPS?
No. On this model the TPS is integrated into the electronic throttle body. If the TPS fails testing or throws correlation codes, the proper repair is replacing the entire throttle body assembly, then carrying out an idle/throttle learn.

What are the common signs of a failing TPS on a 2016 Accord?
Typical clues include the check engine light, sluggish or jumpy throttle, surging at cruise, stalling at idle, and sometimes a “limp” feel. Scan tool codes like P0121–P0123, P0222–P0223, or P2135 often show up. Always confirm with live data and pinpoint tests before parts go in.

Do I need a relearn after throttle body work?
Yes. After cleaning, replacement, or PCM battery resets, perform an idle/throttle position relearn. Using Honda HDS or a capable scan tool is best, but a manual idle learn (warm engine, all loads off, idle for several minutes, then road test) can help the PCM settle trims.
