P0135

Affected Component

Exhaust System

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

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

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

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

Prevention Tips

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.
