2005 Honda Element

What problems might have caused this code?  How can I correct it?  Engine code is P0135


Honda Code P0135

Description: Oxygen Sensor Heater Circuit (Bank 1, Sensor 1)

Code P0135 Probable Causes

  1. Oxygen Sensor or solenoid faulty
  2. Connector terminal contact is damaged or corroded
  3. Wire harness – Check harness for correct voltage, open, short to ground or short to voltage
  4. Open fuse

What does Code P0135 mean?

The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. The code is triggered when the sensor is taking too long to warm up. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors. If the sensor and connector are OK, replacing the O2 Sensor 1 usually takes care of the problem.
