P0135 2006 Ford Fusion Code - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1
Quick Answer
During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. Common causes include Vacuum hose disconnected on exhaust gas recirculation (EGR) system module (ESM) applications, Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1, Heated Oxygen Sensor (H2OS) Bank 1 Sensor 1 circuit fuse. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

2. What are the symptoms of code P0135 on a 2006 Ford Fusion?
Symptoms may include the check engine light turning on, increased emissions, poor fuel efficiency, and potentially rough idling.
3. What causes the P0135 code on a 2006 Ford Fusion?
Common causes include a faulty oxygen sensor, a blown fuse, damaged wiring or connectors, or issues with the vehicle’s powertrain control module (PCM).
4. Which oxygen sensor is Bank 1 Sensor 1 on a 2006 Ford Fusion?
Bank 1 Sensor 1 is the upstream oxygen sensor located before the catalytic converter on the side of the engine with cylinder 1.
5. Can I drive my 2006 Ford Fusion with a P0135 code?
While the car may still be drivable, ignoring the issue can lead to reduced fuel efficiency, increased emissions, and potential damage to the catalytic converter over time.
6. How do I fix the P0135 code on a 2006 Ford Fusion?
Repairs may include replacing the faulty oxygen sensor, repairing damaged wiring, checking the fuse for the sensor’s heater circuit, or addressing PCM issues if necessary.
7. How do I diagnose the P0135 code on a 2006 Ford Fusion?
Use a multimeter to check the oxygen sensor’s heater circuit for continuity, inspect wiring and connectors for damage, and test the fuse and voltage supply to the sensor.
8. How much does it cost to fix the P0135 code on a 2006 Ford Fusion?
Replacing an oxygen sensor typically costs $150–$400, depending on labor rates and parts. Costs may vary if wiring or PCM repairs are needed.
9. Can a bad oxygen sensor cause other problems in my 2006 Ford Fusion?
Yes, a faulty oxygen sensor can lead to poor fuel economy, increased emissions, and long-term damage to the catalytic converter if not addressed.
10. Will clearing the P0135 code with a scanner fix the problem?
Clearing the code will turn off the check engine light temporarily but won’t fix the underlying issue causing the code to appear.
