Manufacturer summary

Original wording in English

Some customers may experience the CHECK ENGINE light ON with DTC P2229:00 stored in PCM memory. à ̄‚· P2229:00 (BARO sensor circuit high input). This concern will most likely occur on vehicles that have aftermarket wax applied in the engine compartment. Aftermarket wax applied in the engine compartment may adhere on the breather hole located at the bottom of the PCM, which may collect dust and result in a plugged filter. This breather hole is actually a filter for the air pressure sensor in the PCM. When the PCM gets hot, the internal air pressure may rise due to the plugged filter and result in DTC P2229:00. To eliminate this concern, the shape of the PCM bracket has been modified to not cover the breather hole and eliminate a gap between it and the PCM that may promote the residual liquid wax.
