On <strong>electronic throttle control (ETC / drive-by-wire)</strong> systems — used on Mitsubishi from approx. 2008 onwards — the IAC valve is NOT fitted; idle is controlled directly by the ETC throttle motor. Vehicles using 1450A132 / MD619857 have cable-operated throttles.</p> <p class="qf-para">Three failure mechanisms: <strong>(1) carbon deposit accumulation</strong> on pintle and bypass passage (PCV oil vapour blow-by); <strong>(2) stepper motor coil burnout</strong> (often caused by underlying vacuum leak forcing IAC to max extension); <strong>(3) pintle wear / spring fatigue</strong> on high-mileage applications. <strong>Always inspect and resolve vacuum leaks BEFORE replacing IAC</strong> — vacuum leak masquerades as IAC fault.</p> </div> </div> </div> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b2')"> <div class="b-title">Symptoms & Diagnostics</div> <div class="b-chevron open" id="qf-chevron-b2">▲</div> </div> <div class="b-body open" id="qf-body-b2"> <div class="qf-symptom"><strong>Engine stalls when coming to stop or engine stalls when A/C engages</strong> — Classic IAC failure symptom. The ECU is unable to raise idle air bypass quickly enough to compensate for sudden load changes (A/C compressor engagement, automatic transmission shift to Drive, electrical load step changes). IAC pintle is sticking or stepper motor is failing to respond to command pulses promptly.</div> <div class="qf-symptom"><strong>Idle speed too high (above 1000 RPM) when engine is warm</strong> — IAC pintle is stuck in the extended position, either from carbon deposits or mechanical seizure. Engine cannot reach normal warm idle (typically 650-850 RPM); ECU cannot retract IAC to correct position. Visual inspection of IAC after removal typically shows heavy carbon buildup on pintle.</div> <div class="qf-symptom"><strong>Idle speed too low (below 600 RPM) or engine stalls at idle</strong> — IAC pintle stuck in retracted position, either from carbon obstruction in the air bypass passage or stepper motor coil failure preventing extension. Engine cannot maintain stable idle; symptoms worsen with cold engine, A/C engagement, or alternator load.</div> <div class="qf-symptom"><strong>Idle speed hunting / surging (RPM rising and falling continuously at idle)</strong> — ECU is attempting to hold idle target but IAC response is inconsistent — either from carbon-restricted pintle movement, partial stepper coil failure, or intermittent connector fault. ECU commands continuous correction creating oscillation. Symptom often worse at cold start, may stabilise after warm-up.</div> <div class="qf-symptom"><strong>Check Engine light with DTCs P0505, P0506, P0507, P0508, P0509</strong> — Idle Air Control System / Circuit fault codes. P0505 (IAC system malfunction), P0506 (idle speed lower than expected), P0507 (idle speed higher than expected), P0508/P0509 (IAC circuit electrical fault). <strong>Mitsubishi-specific DTCs</strong> on some applications: P1602 / P1603 (IAC sensor / actuator).</div> <div class="qf-symptom"><strong>Cold start runs OK but idle deteriorates after warm-up or vice versa</strong> — Temperature-dependent IAC fault — carbon deposits expand / contract with temperature, or stepper motor coil resistance drifts with heat. Pintle movement that works cold may bind when engine warm. Replace IAC valve.</div> <div class="qf-info-box"><strong>Diagnosis sequence:</strong> (1) <strong>First inspect for vacuum leaks</strong> (cracked hoses, leaking PCV, intake manifold gasket, brake booster) — leaks masquerade as IAC fault. (2) <strong>OBD-II scan</strong> for P0505-P0509 (IAC system) and P1602/P1603 (Mitsubishi-specific). (3) <strong>IAC step count live data</strong> — healthy warm idle = 10-30 steps; above 50 = vacuum leak compensation; at 0 or max (255) = ECU saturation. (4) <strong>Visual inspection</strong> for carbon deposits (can be cleaned). (5) <strong>Coil resistance check</strong> — healthy = 28-33 ohms per coil pair. (6) <strong>Pintle movement test</strong> with 12V pulses — should move in discrete steps; binding confirms mechanical fault.</div> </div> </div> </div> <div class="qf-block"> <div class="b-section"> <div class="b-header" onclick="qfToggle('b3')"> <div class="b-title">Logistics & Customs</div> <div class="b-chevron open" id="qf-chevron-b3">▲</div> </div> <div class="b-body open" id="qf-body-b3"> <table class="qf-logistics-table"> <tr><td>International HS Code</td><td>8409.91</td></tr> <tr><td>EAEU Customs Code (TN VED)</td><td>8409 91 000 0</td></tr> <tr><td>Country of Manufacture</td><td>China</td></tr> <tr><td>Quality standard</td><td>IATF 16949</td></tr> <tr><td>Hazardous goods</td><td>No</td></tr> <tr><td>Shipping weight per piece</td><td>0.1 kg (100 grams)</td></tr> <tr><td>Packaging</td><td>Individual sealed bag with part label and moisture-proof packaging</td></tr> </table> <p style="font-size:12px;color:#888;margin-top:12px;font-style:italic">Note: ok.parts listing shows HS 9031.80 (measuring instruments) which is consistent with the incorrect "Throttle Position Sensor" categorisation.

Use throttle body cleaner spray and a lint-free cloth to remove carbon — do NOT use abrasive brushes or solvents that damage the stepper motor seals. <strong>However</strong>: if stepper motor coil has failed (open circuit or short on resistance check), or if pintle is mechanically seized despite cleaning, full IAC valve replacement is required. Also address the underlying source of carbon — service the PCV system (replace PCV valve if old, clean intake manifold) to prevent rapid recurrence.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Does the IAC valve require a relearn procedure after replacement?</div> <div class="qf-faq-a">Most Mitsubishi applications with 1450A132 / MD619857 IAC valves perform automatic adaptation after replacement — the ECU monitors idle airflow vs commanded step count and progressively updates its internal step-to-airflow map. The procedure: (1) disconnect battery for 30 seconds to reset ECU adaptive memory; (2) install new IAC; (3) start engine WITHOUT touching accelerator; (4) allow to idle for 5-10 minutes; (5) test drive. <strong>On Mitsubishi applications using MUT-II or MUT-III diagnostic tools</strong>: a manual "IAC reset" command can be issued to force adaptive learning reset; this is optional but recommended if idle does not stabilise within 5-10 minutes after installation. On Chrysler / Dodge applications with the Mitsubishi-sourced 3.0L V6, no specific relearn procedure is required.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Will replacing the IAC valve fix a vacuum leak symptom?</div> <div class="qf-faq-a"><strong>No.</strong> Vacuum leaks produce identical symptoms to IAC failure (high idle, hunting, stall at load) because ECU uses IAC to compensate for unmetered airflow. <strong>Always resolve vacuum leaks BEFORE replacing IAC</strong>. Smoke test intake; inspect vacuum hoses; verify PCV. If IAC step count reads below 5 steps at warm idle, vacuum leak is highly probable. Replacing IAC will not fix the underlying leak.</div> </div> <div class="qf-faq-item"> <div class="qf-faq-q"><span class="qf-faq-q-icon">Q</span>Is white-label or custom packaging available for Mitsubishi specialist distributors?</div> <div class="qf-faq-a">Yes. ok.parts sources directly from manufacturing facility. White-label packaging with vehicle / component label (Mitsubishi IAC valve for Lancer / Eclipse / Galant / Outlander / Montero / Pajero IO / Chrysler Sebring / Dodge Stratus 1999-2013) available for wholesale distribution. <strong>Cross-platform compatibility</strong> with Chrysler / Dodge expands addressable market.

Reusing old seal = vacuum leak that reproduces all original symptoms immediately after replacement.</td> </tr> <tr> <td>PCV Valve</td> <td>Mitsubishi-specific PCV valve (varies by engine: 4G15 / 4G93 / 6G72 / 6G74)</td> <td>PCV system is the primary source of carbon deposits on IAC valve and in throttle body. If old IAC failed from carbon buildup, replace PCV valve simultaneously to prevent rapid recurrence on the new IAC. Inexpensive maintenance item that protects the higher-cost IAC replacement investment.</td> </tr> <tr> <td>Throttle Body Gasket</td> <td>Mitsubishi throttle-body-to-intake-manifold gasket (varies by engine)</td> <td>If throttle body is removed for thorough cleaning during IAC service, new gasket is required for reinstallation. Old hardened gasket will leak vacuum after disturbance. Inspect gasket condition at IAC service.</td> </tr> <tr> <td>Intake Manifold Gasket Set</td> <td>Mitsubishi intake manifold gasket / O-ring set (engine-specific)</td> <td>Intake manifold gasket failure produces same symptoms as IAC failure (vacuum leak = high idle / hunting / stall). If diagnostic confirms vacuum leak rather than IAC fault, intake manifold gasket replacement is the correct repair. Inexpensive insurance during major intake service.</td> </tr> <tr> <td>Throttle Body (if damaged / corroded)</td> <td>Mitsubishi throttle body assembly (engine-specific reference)</td> <td>If IAC mounting bore in throttle body is damaged, corroded, or scarred from incorrect previous service operations, IAC will not seal reliably. Full throttle body replacement may be required if bore damage cannot be cleaned and restored.</td> </tr> </tbody> </table> </div> </div> </div> </div> <script> function qfToggle(id){ document.getElementById('qf-body-'+id).classList.toggle('open'); document.getElementById('qf-chevron-'+id).classList.toggle('open'); } </script>
