Customer: pO 122, PO107....hard set, will erase but come right back.
JA: Are you fixing your Montero yourself? What have you tried so far?

Click on link to see the Troubleshoot of the DTC P0107 & DTC P0122

after running the dtc steps and repair or replace then you clear fault codes ,and test drive and see what comes back if any , I think the dtc PO122 will clear after repairing dtc P0107, but testing is needed

Thanks. Will go thru the troubleshooting steps you attached.... I am owner, not mechanic. Now I know the two ends of the power wire, so I can check continuity, and output right at the source also.
