The check engine light on. I had the local autoparts store to run a scan and it showed that bank 2 oxygen sensor heater circuit had malfunctioned. I purchased a new O2 sensor and had a local mechanic to install it. After the installation he scanned the ECM again, reset the fault code and everything showed to be working fine. The following day, the check engine light came back on. I had the mechanic to scan it again and it showed to be the same O2 sensor. It was replaced again with another new sensor, reset and everything once again showed to be working properly. The check engine light came on again the following day. Had the local autoparts store to scan again and it came up showing the same O2 sensor with heater circuit malfunction. Please help with any information. Not sure what to do now.
have the same problem?
