PERFORMANCE ORDER

1. Start the engine and warm it up to normal operating temperature
2. Leave the engine running at idle speed.
	3. Connect a voltmeter between terminals 2 (wire GRN / BLU) and ground.
4. Several times increase and decrease the speed of the engine.
5. Verify that the voltage varies 0-1,0V.
A warning The voltage at the rear oxygen sensor does not change as quickly as the front sensor.
6. Otherwise, check: - On-board diagnostics system; - Check the system; - Check the vacuum in the intake manifold; - Check the fuel pressure.
7. If all systems are normal, replace the oxygen sensor.
