4. Honda Odyssey P0201 FAQs
What causes code P0201 to trigger on a Honda Odyssey?
On the Honda Odyssey (3.5L SOHC VTEC V6 (280HP / 10-Speed Auto)), P0201 is most frequently caused by Failed, open, or shorted fuel injector solenoid on Cylinder 1 or Damaged or chewed wiring harness to Cylinder 1 injector.
Where is the OBD-II port located on my Honda Odyssey?
On the Honda Odyssey, the 16-pin DLC diagnostic connector is located Under driver dash, behind small flip cover near hood release. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Honda Odyssey with code P0201?
No. Dead injector on Cylinder 1 causes immediate dead misfire, severe shaking, and unburned air/fuel delivery imbalance. Given that P0201 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
