2003 Mazda6 2.3L AT - P0841 Code: Transmission Pressure Sensor 'A' Circuit Range/Performance Issue

Model: 2003 mazda 6 Fault Code: P0841 Posted: 2010-08-04 09:28

I recently replaced the engine in my 2003 Mazda6 2.3L with an automatic transmission, and it's running smoothly now. However, this morning the vehicle exhibited hesitation when shifting into gear for a few minutes before responding normally. The AT warning light briefly illuminated on the dashboard and then turned off. The check engine light has triggered a P0841 diagnostic code: 'Transmission Pressure Sensor/Switch A Circuit Range/Performance'. Given that the issue appears to occur intermittently, I suspect it might be related to wiring or sensor connectivity. Any insights or troubleshooting steps for this specific code on a 2003 Mazda6 with an automatic transmission would be greatly appreciated. Thanks, Chris
