NHTSA Service Bulletin 10228855: 2019-2022 Ford Ranger
Official manufacturer communication context for 2019-2022 Ford Ranger, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
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.
