2001 Hyundai Elantra Repair Question
Asked on July 11, 2012
Any chance it won't go off?
Hi
I replaced both O2 sensors with original hyundai sensor(after cat and before cat) in Jan. 2012-I just cleaned carbon from engine with seafoam. The CEL is now on, my question is will cleaner(seafoam) throw my readings off that greatly as to set off the CEL? and will it go off when the readings stabilize?

Codes are PO136/PO140 and PO141-possible got a bad O2 sensor-just changed both in Jan. 2012- Hyundai dealer I would hope they checked the circut before they replaced the sensor!

Oxygen sensor problem:If the codes are still coming back-They should check the wiring and the computer
