2024 Jeep Grand Wagoneer L Check Engine Light Codes

In Danvers, MA, Herb Chambers Chrysler Dodge Jeep RAM FIAT of Danvers provides expert diagnostics for the 2024 Jeep Grand Wagoneer L that target the most common check engine codes quickly and accurately. Typical codes we see include P0420 (catalytic converter efficiency), P0300 (random/multiple cylinder misfires), P0136–P0167 (oxygen sensor circuits), and P0101 (mass airflow sensor range).

Misfires can cause engine damage and reduced towing reliability—critical for owners who use the Wagoneer L’s 9,450-lb towing capacity. Our certified technicians use OEM diagnostic tools and genuine parts, which maximizes repair longevity and often delivers lower total cost than multiple independent fixes. We always explain repair options, warranty coverage, and the immediate and long-term savings of professional, certified service at our Danvers facility.
