Cadillac Connection Woes
This bulletin applies to 2016-2018 Cadillac CTS-V and 2015-2018 Escalade vehicles equipped with a 6.2L LT4 or L86 engine. The SES lamp may be on, with DTC P0333 when shifting the transmission from the park position. This DTC can be set due to voltage from the transmission park/neutral signal 1 circuit bleeding into the knock sensor system circuits. If service manual diagnostics do not isolate the problem, inspect the K20 ECM connector X2 looking for debris, connector or terminal concerns.
