• 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
• P0191Fuel rail pressure sensor circuit performance. Inconsistent sensor signal rather than actual low pressure. Check wiring and connector; replace sensor if signal remains erratic
• P0201P0208 - Fuel injector circuit fault, cylinders 1-8. Failed injector, wiring damage, or failed PCM driver. On 5.7L Hemi, injector code alongside a misfire on the same cylinder strongly suggests a failed injector. Swap injector to confirm
• P0325Knock sensor circuit fault, Bank 1. Failed sensor, wiring fault, or corroded connector. On 5.7L Hemi, oil sludge from deferred changes can affect signal. Inspect connector first
• P0365Camshaft sensor circuit fault, Bank 1 Sensor B. Failing exhaust cam sensor on 3.6L Pentastar or restricted VVT oil control valve from sludge. Clean OCV passages; replace sensor if passages are clear
• P0390Camshaft sensor circuit fault, Bank 2. On Hemi combined with P0340, confirms stretched timing chain beyond tensioner range. Timing chain kit replacement required
• P0404EGR valve position sensor performance. Carbon buildup on EGR valve - common on 6.7L Cummins diesel Ram. Clean or replace EGR valve; scheduled maintenance item on diesel models
• P0420Catalyst efficiency below threshold, Bank 1. Under 100,000 miles: failed upstream O2 sensor. Past 150,000 miles: converter at end of life. Running with misfire codes: misfires have damaged the substrate. Confirm O2 sensor function before replacing converter
