Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering powertrain on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
Certain vehicles equipped with the Intelligent Variable Transmission (IVT) may experience a check engine light or malfunction indicator light due to Diagnostic Trouble Codes (DTC) listed below. This bulletin provides information on replacing the oil pressure sensor to remedy these DTCs, rather than replacing the entire IVT assembly.
full bulletin at NHTSA ↗If you are servicing an applicable vehicle with a âCheck Engineâ light on and one or more of the DTC listed on Page 2, follow the repair procedure and perform the diagnosis. If necessary, replace the High Flow electric oil pump (HF EOP) for HF EOP issues or the Dual Clutch Transmission for High Pressure electric oil pump (HP EOP) issues.
