Can a bad EGR valve cause O2 sensor code?

Can a bad EGR valve cause O2 sensor code?

Any vacuum leak, including the leak in the EGR valve control system that you described, could cause the P0153 code. If the two codes do not recur, you should still check the output of the oxygen sensor for correct waveform and output (switching between 0.2 to 0.9 volts).

What happens when the EGR sensor goes bad?

If the EGR pressure sensor sends any false reading to the computer it can cause the EGR system to malfunction. A malfunctioning EGR system can lead to engine performance issues such as rough idle, engine hesitation, and a decrease in overall power and fuel efficiency.

Can you drive with a bad EGR sensor?

Can I drive with a bad EGR valve? Technically, you can drive your vehicle with a bad EGR valve, but your vehicle will run rough, shake at idle, and a check engine light will be illuminated. You might also hear popping sounds while driving down the road.

How can I tell if my EGR valve is stuck open?
