On some cars it could, depends on code.
Its the code for the torque converter clutch solenoid.
A failed catalytic converter is one of hundreds of parts that can cause the check engine light to be on.
To line up the torque converter to the flywheel, first, ensure that the torque converter is fully seated into the transmission pump. Then, align the converter's mounting holes with the flywheel's holes, ensuring that the converter is positioned properly so that it engages the engine's flexplate or flywheel correctly. Rotate the engine by hand if necessary to align the bolt holes, and then securely fasten the torque converter to the flywheel with the appropriate bolts. Finally, double-check that the converter is not binding and that it spins freely.
