"Service Bulletin - The PCM software may misinterpret sensor inputs as a deteriorated catalytic converter. Additionally, debris from the high pressure pump or the fuel injector machining process can cause internal wear or clogging inside one or more injectors. One or more of the following DTCs may be stored: - P0420 (rear bank catalyst system efficiency below threshold [bank 1]) - P0430 (front bank catalyst system efficiency below threshold [bank 2]) - P0300-P0306 (misfire) - P219A (air-fuel ratio variation of cylinder [bank 1, rear bank]) - P219B (air-fuel ratio variation of cylinder [bank 2, front bank]) American Honda is extending the warranty on these repairs to 10 years from the original date of purchase or 150,000 miles, whichever comes first."

Service Bulletin - MIL Comes On with DTC P0300-P0306 or P219A/B

FORD · 2021-02-02

Some 2017-2021 Ford GT vehicles may exhibit a runs rough or hard start with or without an illuminated MIL with DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306 and/or P0316. Prior to performing any diagnostics, determine if the vehicle operating conditions may have resulted in multiple cold engine start-ups without allowing the engine to reach normal operating temperature and being driven. If that operating condition is determined, inspect the spark plugs per Workshop Manual (WSM), Section 303-00 and repair as directed. If no concern with spark plugs are found, proceed with normal diagnostics per the Powertrain Controls/Emission Diagnosis (PC/ED) Manual. Upon returning the vehicle, refer the customer to the owners guide regarding proper driving cycles.

Customer?s complaint may include a MIL-on with one or more of the following DTCs (Active, Pending, or Stored) in the PCM: P0133, P0137, P0171, P0300, P2096. The root cause could be due to oil leaking from Bank 1 valve cover seal on to the 1/2 (Bank 1 downstream) O2 sensor. This can adversely affect the 1/2 O2 sensor signal reading and lead to listed DTCs. Before performing normal diagnostic routines for the above codes, check for the condition listed above.

MAZDA · 2021-01-14

Some vehicles may exhibit an occasional rough idle accompanied with DTC P0300:00 (Random misfire) due to the following: 1. While closing the EGR valve, carbon deposit etc. pinched at the valve seat prevents the valve from closing completely. 2. The closed position of the EGR valve is learned improperly as it is not equipped with a position sensor. 3. While idling, the EGR gas improperly mixes in fresh air through the EGR valve that is not closed properly. 4. Misfire occurs. To eliminate this concern, the control software of the PCM has been modified to force the learning of the closed position of the EGR valve when a misfire is detected at idle
