They may also comment that they intermittently are unable to shift into Reverse. When checking the vehicle for DTCs, the engine control module (ECM) may report P0502 as current or in history. This may be caused by water intrusion into the vehicle’s manual transmission output speed sensor or could be induced by the customer slipping the clutch for an extended period of time, as in holding the vehicle on a hill.","document":null,"url":"https://open.wenmarpro.com/bulletins/10075717","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"manual-transmission","name":"Manual transmission","parent":"powertrain"}],"codes":["P0502"],"topics":[],"vehicles":[{"make":"CADILLAC","model":"ATS","year_from":2013,"year_to":2016,"match":"exact","vehicle_ids":["2013_cadillac_ats","2014_cadillac_ats","2015_cadillac_ats","2016_cadillac_ats"]},{"make":"CADILLAC","model":"ATS-V","year_from":2016,"year_to":2016,"match":"base","vehicle_ids":["2016_cadillac_ats"]},{"make":"CHEVROLET","model":"CORVETTE","year_from":2014,"year_to":2015,"match":"exact","vehicle_ids":["2014_chevrolet_corvette","2015_chevrolet_corvette"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
