Error Code
P0135
Affected Component
Exhaust System
Estimated Time
1-2 hours

Safety Warnings

  • ⚠Disconnect battery before working on electrical systems.
  • ⚠Allow the engine to cool before working on exhaust components.

Symptoms

  • •Check engine light illuminated
  • •Poor fuel economy
  • •Rough idle
  • •Engine stalling during acceleration
  • •Increased emissions
  • •Failure to pass emissions test

Diagnostic Steps

  1. 1Scan the vehicle's OBD-II system to confirm the P0135 code and check for any additional codes.
  2. 2Inspect the wiring and connectors leading to the upstream oxygen sensor for damage or corrosion.
  3. 3Use a multimeter to test the resistance of the oxygen sensor heater circuit.
  4. 4Check the fuse related to the oxygen sensor heater circuit.
  5. 5Verify the voltage supply to the oxygen sensor heater circuit with a multimeter.
  6. 6Inspect the oxygen sensor for physical damage or contamination.

Solution

Solution

1. Preparation

  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on the electrical system.

2. Inspect and Repair Wiring

  • Remove any protective coverings to access the wiring of the upstream oxygen sensor.
  • Check for any frayed, broken, or corroded wires.
  • Repair or replace any damaged wiring as necessary, ensuring a secure connection.

3. Replace Oxygen Sensor

  • Tools Required: O2 sensor socket, wrench set, torque wrench, dielectric grease.
  • Locate the upstream oxygen sensor on the exhaust manifold.
  • Disconnect the electrical connector from the oxygen sensor.
  • Use the O2 sensor socket to unscrew the old sensor from the exhaust.
  • Apply dielectric grease to the threads of the new sensor.
  • Install the new oxygen sensor and tighten it to the manufacturer's specified torque (typically around 30 Nm).
  • Reconnect the electrical connector.

4. Check and Replace Fuse (if necessary)

  • Locate the fuse box and find the fuse for the oxygen sensor heater circuit.
  • Use a multimeter or visual inspection to determine if the fuse is blown.
  • Replace the fuse with one of the same amperage if necessary.

5. Reconnect Battery and Clear Codes

  • Reconnect the battery terminals.
  • Use the OBD-II scanner to clear the P0135 code from the system.

Verification

After completing the repair, verify that the issue has been resolved:

  • ✓Test the affected component to ensure it functions correctly
  • ✓Check for any error codes or warning lights
  • ✓Monitor the vehicle for a few days to ensure the issue does not recur
