The code P0129 on a 2005 Dodge Magnum indicates that the Engine Control Module (ECM) has detected a problem with the Barometric Pressure (BARO) sensor or the input from the intake manifold pressure sensor. This code typically suggests that the atmospheric pressure reading is lower than expected, which can affect engine performance and efficiency. Common causes include a faulty BARO sensor, vacuum leaks, or issues with the wiring and connectors. It's advisable to diagnose the specific issue to ensure proper repairs.
P0129-BAROMETRIC PRESSURE OUT-OF-RANGE
You have to fix the cause of the code that is set in the ABS module.
Egr valve, PCM, or wires in between. Those are the causes.
A P0129 code on a 2009 Dodge Charger indicates a problem with the barometric pressure sensor or a related issue, typically related to insufficient intake air pressure. To fix this, first inspect the intake air system for any leaks or blockages, and check the wiring and connectors to the sensor for damage. If everything appears intact, consider replacing the barometric pressure sensor. Finally, clear the code and test drive the vehicle to see if the code returns.
The airbag light stays on when there is a malfunction. The airbag computer will have stored a trouble code. When the failure is repaired the light will shut itself off.
Trouble code P0401 means:Exhaust gas recirculation flow insufficient detected
Trouble code P0944 means: Hydraulic pressure unit loss of power
Trouble code P1470 means: Leak Detect Pump Pressure Switch Low
P0562 System Voltage Low
Cylinder #7 Misfire
I would double check that that is the actual code stored in the PCM. That is a code for EGR and you are correct that you do not have EGR.
Trouble code P0700 means:Transmission control system malfunction
