2002 Honda Odyssey P0170 and P0172 Diagnostic Guide
2002 Honda Odyssey with 421,000 miles is showing both DTCs P0170 and P0172. The Check Engine Light is on, and I'm looking for clear guidance on where to begin diagnosing this issue. Any technical advice or common causes related to these codes in a 2002 Honda Odyssey would be greatly appreciated. Thank you!
Begin by checking fuel pressure and leak-down tests, as both are common factors contributing to P0170 and P0172 in older Honda Odysseys.
