P0507 on Ram vehicles
Idle Higher Than Expected — what it means on a Ram, whether it's safe to drive, and the fixes by model and year.
P0507 on a Ram means idle higher than expected. Most vehicles stay drivable short-term, but diagnose it promptly. The most common cause is vacuum leak (intake gasket, pcv hose, brake-booster hose, throttle-body gasket) (typically $80–$600). Pick your Ram model below for its known failure patterns, recalls, and TSBs.
What does P0507 mean on a Ram?
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.
P0507 is a standardized OBD-II code, so its definition is the same on every Ram. What differs by model and engine is which cause is most likely — pick your Ram model below for a diagnosis tuned to its known failure patterns, recalls, and TSBs.
Is it safe to drive a Ram with P0507?
In most cases a Ram stays drivable for short trips with P0507 active, but diagnose and repair it promptly. This is a moderate-severity code — ignoring it can lead to further damage or a failed emissions test. Exact tolerance depends on the model and engine.
What causes P0507 on a Ram?
| Cause | Likelihood | Estimated repair (USD) |
|---|---|---|
| Vacuum leak (intake gasket, PCV hose, brake-booster hose, throttle-body gasket) — Most P0507 codes trace to unmetered air entering the engine. | Most common | $80–$600 |
| Carbon-coked throttle body keeping the blade slightly open | Common | $20–$200 |
| Failed or sticking idle air control (IAC) valve on older non-ETC vehicles | Common | $80–$300 |
| Failed throttle body needing replacement and relearn | Occasional | $250–$800 |
| Sticking accelerator pedal or throttle cable (older vehicles) | Occasional | $50–$250 |
| Cracked plastic intake manifold | Occasional | $250–$900 |
| EVAP purge valve stuck open (often sets P0496 alongside) | Occasional | $80–$300 |
Repair costs are typical US ranges and vary by Ram model, model year, and labor rate. A diagnostic trouble code is a symptom, not a guaranteed failed part — confirm the root cause before replacing anything.

What are the symptoms of P0507 on a Ram?
Check Engine Light is illuminated. Engine idles noticeably high (1000-1500 RPM instead of 700-900). Possible whistling or hissing sound from the intake area. Reduced fuel economy. Hesitation as the engine tries to slow when stopping. May be paired with P0171 (lean code)
