2024 Jeep Grand Wagoneer L Check Engine Light Codes

The 2024 Jeep Grand Wagoneer L in Boise may throw common codes such as P0300 (random/multiple misfires), P0420 (catalyst efficiency below threshold), P0171 (system too lean), P0455 (evaporative emissions large leak), and P0191 (fuel rail pressure sensor). Each code points to distinct risks: misfires can lead to bent rods and expensive engine damage; untreated catalytic problems often result in a converter replacement that can exceed a thousand dollars; lean conditions increase turbocharger stress and reduce engine life; EVAP leaks harm emissions compliance and can trigger failed inspections. At Larry H. Miller Chrysler Jeep Dodge Ram Boise our factory-trained technicians use OEM-grade tools to identify root causes and recommend cost-effective repairs. Acting early saves you money on fuel and expensive downstream parts. We offer clear estimates, warranty verification, and OEM parts so repairs are done right the first time.
