What is the reason why the Mazda 6 P gear does not display and cannot start?
2 Answers
Mazda 6 P gear does not display and cannot start due to reasons such as battery not supplying power, incorrect gear position, or fuel line blockage. Below are the specific reasons for the Mazda 6 P gear not displaying: Battery not supplying power: There are three situations where the battery does not supply power: excessive discharge, continuous discharge, or electrode corrosion. Incorrect gear position: Automatic transmission owners should be aware that if the gear is not in P or N, the car will not start. Similarly, for some manual models, if the clutch is not pressed when starting, the same issue occurs. This situation is more likely to happen to owners with mischievous children at home or beginners. Fuel line blockage: Some owners may add cheaper fuel to save on household expenses, leading to blockages.
I've been driving a Mazda 6 for several years and encountered the annoying issue where the P gear doesn't display and the car won't start. There are usually several reasons for this. First, it could be a key system problem, such as a dead smart key battery or the anti-theft function locking the ignition, causing the P gear light on the dashboard not to illuminate. Second, it might be a faulty transmission position switch, which is hidden under the gear lever—if it gets dirty or worn out, it can't detect the P gear position, and the ECU won't allow ignition. Wiring issues are also common, like blown fuses or loose connectors, especially in rainy weather when corrosion is likely. Poor battery terminal contact can also trigger this type of error. Here's what I suggest for simple troubleshooting: try starting the car by bringing the key close to the steering wheel, or replace the battery; check the fuse box in the engine compartment and replace the ignition-related fuse; if that doesn't work, take it to a professional repair shop. Don’t neglect key maintenance and keeping the car dry during washes—small issues like this can damage the car over time. The Mazda 6's design is quite sensitive to electrical systems, so regular maintenance can prevent most of these troubles.
