Understanding P0135 on Your 2022 Titan
Your 2022 Nissan Titan has triggered a P0135 diagnostic code, indicating a malfunction in the oxygen sensor heater circuit for Bank 1, Sensor 1. The 2022 Titan is powered by a 5.6L V8 Endurance engine (400 hp). On this V8, Bank 1 is the driver's side cylinder bank, and Sensor 1 is the upstream O2 sensor.
At 2-3 years old, your Titan should have warranty coverage for this repair.
Symptoms
- Check engine light on
- Slightly reduced fuel economy
- Rough cold idle
- Emissions test failure
Common Causes
O2 Sensor Heater Element Failure
Manufacturing variation or early wear. The V8's high exhaust output stresses sensors.
Connector or Wiring Issue
Truck duty and towing can stress connections.
Blown Fuse
Check the O2 heater fuse first.
Warranty Coverage
- Bumper-to-Bumper: 3yr/36k (may still apply)
- Powertrain: 5yr/60k

V8 Truck Considerations
The Titan's V8 produces significant exhaust heat. If used for towing or heavy work, O2 sensors may wear faster. The V8 has four O2 sensors total—two per bank.
