Modern engines often display CHECK ENGINE after decat or when running on LPG. This problem can be solved by using this simple lambda probe extender. The secondary lambda probe (after the cat) should be reinstalled with this extender. This solves problems caused by the secondary O2 sensor, and prevents the engine from entering service mode. Please note: after installation, you may need to reset the engine ECU to remove 'Check Engine' light.

Package Include： 1PC Oxygen Sensor
