P0135 on the 2022 Honda Odyssey
The 2022 Honda Odyssey uses the 3.5L J35Y7 V6 engine (280 hp) with a 10-speed automatic transmission. A P0135 code means the heater circuit in the Bank 1 upstream O2 sensor has malfunctioned. On the Odyssey's transverse V6, Bank 1 is the rear bank nearest the firewall. The heater element rapidly warms the sensor after each engine start for cold-start emissions control.
Minivan Usage and Heater Wear
The Odyssey's role as a family vehicle means it endures a high number of short-trip cold starts: school pickups, errands, activities, and short commutes. Each cold start activates the O2 sensor heater, and this high cycle count per mile driven means the Odyssey's sensor heaters accumulate more stress than vehicles used primarily for highway driving. While the 2022 model is relatively new, early heater failure can occur if the vehicle has accumulated a high number of cold-start cycles.
Causes
- Premature heater element failure: Even on a newer vehicle, high cycle counts from frequent short trips can stress the heater element. A manufacturing variation in the heater wire resistance can also cause premature failure.
- Blown heater fuse: The underhood fuse box has a dedicated O2 heater fuse. This is the first and easiest thing to check.
- Connector issue: The rear bank sensor connector may have developed corrosion from road spray, or may have an assembly defect in pin seating.
- Wiring concern: The heater circuit wiring routing behind the V6 can be subject to heat soak, particularly on the rear bank where airflow is limited.
Warranty
Your 2022 Odyssey is covered under Honda's 3-year/36,000-mile basic warranty and the federal 8-year/80,000-mile emissions warranty. The O2 sensor heater repair should be covered at no cost at any authorized Honda dealer.
Dealer Diagnosis
- Code verification with Honda Diagnostic System (HDS).
- Heater fuse inspection and circuit power verification.
- Heater resistance measurement at the sensor connector.
- TSB check for the 2022 Odyssey V6.
- Sensor replacement or circuit repair as needed.
Reference Costs
Under warranty: $0. Post-warranty reference: OEM sensor: $90-$185. Dealer labor for rear bank: $150-$280. Total: $240-$465. Honda dealer labor: $130-$180/hour.
Symptoms and Driving
Check engine light is the primary symptom. The Odyssey drives normally once the engine is warm. Cold starts may be slightly rougher for the first minute. Fuel economy on short trips may decrease marginally. The vehicle is completely safe to drive with this code active.
