Learn how to diagnose and fix P0135 oxygen sensor circuit issue in Renault Clio V. Step-by-step guide with diagnostic procedures and repair instructions.

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.
