Tüm modeller için diğer kodlar

• P0113Intake air temperature sensor voltage high. Open circuit or disconnected connector at the airbox.
• P0117ECT sensor voltage low. Faulty sensor or corroded connector. On 3.6L Pentastar, sensor connector is a known weak point.
• P0122Throttle position sensor voltage low.
• P0128Coolant temperature below thermostat regulating temperature. Thermostat stuck open - most common code on Charger, Durango, and Grand Caravan. Also causes poor heater output and downstream rich codes. Thermostat replacement resolves it in the majority of cases
• P0135Upstream O2 sensor heater fault, Bank 1. Failed heater element inside the sensor. More frequent on 3.6L Pentastar past 120,000 miles. Replace upstream O2 sensor
• P0171System too lean, Bank 1. Vacuum leak, dirty MAF, low fuel pressure, or failing O2 sensor. On Ram 1500 3.6L, intake manifold gasket leaks are a documented cause. Smoke test for vacuum leaks first
• P0172System too rich, Bank 1. Stuck-open injector, failed O2 sensor, or ECT sensor fault. Often appears with P0128 when thermostat is stuck open. Start with thermostat if P0128 is present
• P0175System too rich, Bank 2. When appears with P0172, suspect a shared cause - MAF sensor, ECT sensor, or thermostat - rather than a bank-specific problem
