Bulletin Summary
Some 2019-2022 Ranger vehicles not equipped with an engine appearance cover may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P0300, P0301, P0302, P0303, P0304 and/or P0316 stored in the powertrain control module (PCM). This may be due to water build up in the spark plug well(s) which can lead to signs of corrosion on ignition system components. To prevent reoccurrence, an engine appearance cover must be installed on the vehicle. Currently, the engine cover (SPN: L1MZ-6A949-A) is not available to order and a new engine cover kit is being released. Repair the vehicle by replacing suspect ignition system components and schedule an appointment with the customer to have an engine cover installed when the engine cover kit becomes available in April 2023.

About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
