P2626 - O2 SENSOR POSITIVE CURRENT TRIM CIRCUIT/OPEN (BANK 1 SENSOR 1)
| Description: During deceleration fuel shut-off (DFSO) the PCM monitors the integrity of the UO2SPCT11 circuit by comparing the actual oxygen sensor voltage signal to an expected oxygen sensor voltage signal. This DTC sets when the actual oxygen sensor voltage exceeds the maximum expected voltage threshold for a specified amount of time. | |||
