my 2001 jeep grand cerokee was coding p0138. this was an oxygen sensor. I replace the oxygen sensor and now it is coding for all four oxygen sensors I cleared the codes and it is back on again.

Asked by Jul 10, 2015 at 06:51 AM about the 2001 Jeep Grand Cherokee Limited 4WD

Question type: Maintenance & Repair

I was told that if you change one oxygen
sensor it can make the others go out. Is that
true??

1 Answer

Changing one O2 sensor will not cause any others to go out. O2 sensors get slower to react with age and miles. It is probably a good idea to change both upstream sensors if the vehicle has over 100,000 miles on it. This may result in slightly better fuel mileage.
