P0507 on a 2022 Ford F-150

Idle Higher Than Expected

Severity: moderate Safe to drive (short term) Pickup Truck 2020-2024 Ford F-150

What does P0507 mean on a 2022 Ford F-150?

P0507 is set when the ECM commands the throttle to a specific idle RPM and measures actual idle higher than that target by more than a calibrated amount (typically 200+ RPM higher). The cause is almost always unmetered air entering the engine — a vacuum leak somewhere — or a stuck throttle body / idle control issue.

Symptoms on a 2022 Ford F-150

Likely causes on a 2022 Ford F-150

  1. Vacuum leak (intake gasket, PCV hose, brake-booster hose, throttle-body gasket) Most common
    Estimated repair: $80– $600

    Most P0507 codes trace to unmetered air entering the engine.

  2. Carbon-coked throttle body keeping the blade slightly open Common
    Estimated repair: $20– $200
  3. Failed or sticking idle air control (IAC) valve on older non-ETC vehicles Common
    Estimated repair: $80– $300
  4. Failed throttle body needing replacement and relearn Occasional
    Estimated repair: $250– $800
  5. Sticking accelerator pedal or throttle cable (older vehicles) Occasional
    Estimated repair: $50– $250
  6. Cracked plastic intake manifold Occasional
    Estimated repair: $250– $900
  7. EVAP purge valve stuck open (often sets P0496 alongside) Occasional
    Estimated repair: $80– $300

How to diagnose this on a 2022 Ford F-150

  1. Confirm the actual idle RPM and check fuel trims

    Scan-tool live data should show actual idle RPM and the target. Look at Bank 1 LTFT: a high positive number (e.g. +15 % or more) confirms a real vacuum leak. Trims near zero with high idle point at a throttle body or EVAP issue rather than a leak.

    Tools: Scan tool with live PIDs

  2. Smoke-test the intake

    Pressurize the intake with smoke through a snorkel cap or the throttle body. Watch every gasket, hose, vacuum tee, the brake booster line, the PCV system, and the EVAP purge line. Smoke escaping anywhere is the leak.

    Tools: EVAP / intake smoke machine, Flashlight and inspection mirror

  3. Inspect and clean the throttle body

    Coked carbon at the throttle bore prevents the blade from closing fully — the engine pulls air around the blade that the ECM cannot fully control. Clean with throttle-body-safe cleaner (never carb cleaner) and a soft brush. Perform an idle relearn after.

    Tools: Throttle body cleaner, Soft brush, Service manual for the relearn procedure

  4. Test the IAC valve (non-ETC vehicles)

    On older vehicles with a separate IAC valve, command the valve with a scan tool and watch for idle changes. A valve that does not respond, or that idles correctly with the connector unplugged, is stuck or failed.

    Tools: Scan tool with IAC command

  5. Verify the EVAP purge valve is not stuck open

    A stuck-open purge valve introduces unmetered fuel vapor at idle, causing high idle and lean trims similar to a vacuum leak. With the engine idling, disconnect the purge valve — if idle smooths out, the purge valve is the cause.

    Tools: Hose disconnect tools

About the 2020-2024 Ford F-150

The 2020-2024 Ford F-150 was commonly sold with the following powertrains: 3.5L EcoBoost V6, 5.0L V8, 2.7L EcoBoost V6. Common trims include XL, XLT, Lariat, King Ranch, Platinum.

The vacuum leak almost certainly is the cause

P0507 paired with P0171 (or P0174) is virtually always a vacuum leak. The high idle and the lean fuel trim both result from the same underlying problem: unmetered air entering the engine downstream of the MAF. The ECM cannot identify exactly which leak path is responsible, only that one exists. Smoke testing is the fastest path to the source.

Idle relearn after throttle body cleaning

Modern vehicles with electronic throttle control require an idle relearn after any throttle body removal, cleaning, or replacement. The procedure varies — generally:

  1. Battery disconnect 30+ seconds, reconnect
  2. Key on, engine off, 30 seconds
  3. Start engine, idle 5 minutes with no load (AC off, no electrical accessories)
  4. Drive a short cycle including a few full stops

Some vehicles require a bidirectional scan tool to perform the relearn. Without a successful relearn, P0507 will set again within a few drive cycles even though the throttle body is mechanically perfect.
