Installation Guide

1. Safety First: Allow the engine and exhaust system to cool completely before working. Disconnect the battery to prevent accidental short circuits.
2. Locate Existing Sensor: Identify the current oxygen sensor in the exhaust manifold or catalytic converter housing.
3. Remove Old Probe: Use a suitable socket or wrench to unscrew the old sensor. Carefully detach any wiring harnesses, noting their orientation.
4. Prepare New Sensor: Inspect the Bosch 0258007234 for damage. Ensure the connector aligns with the vehicle’s harness.
5. Install Probe: Thread the new sensor into the exhaust pipe or catalytic converter housing until snug. Tighten to manufacturer specifications (typically 20–25 Nm).
6. Reconnect Wiring: Attach the vehicle‑specific connector, ensuring a secure fit and correct polarity.
7. Re‑connect Battery: Restore power and start the engine. Monitor ECU diagnostics for any fault codes related to the oxygen sensor.
