3. Step-by-Step DIY Repair Guide for Honda Pilot
Locate Cylinder 1 fuel injector. Ensure connector is securely clicked in and wires are not frayed. on the Honda Pilot equipped with 3.5L DOHC 24-Valve V6 (285HP / 10-Speed Auto).
Unplug connector and measure resistance across the two injector pins. Normal is 11–16 ohms for high-impedance injectors. If open (OL) or shorted (0 ohms), replace injector. on the Honda Pilot equipped with 3.5L DOHC 24-Valve V6 (285HP / 10-Speed Auto).

4. Honda Pilot P0201 FAQs
What causes code P0201 to trigger on a Honda Pilot?
On the Honda Pilot (3.5L DOHC 24-Valve V6 (285HP / 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 Pilot?
On the Honda Pilot, the 16-pin DLC diagnostic connector is located Under driver steering column. 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 Pilot 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.
