Code 19 is "A/T Lock-up control solenoid" caused by "Open or shorted signal circuit, lock-up solenoid" and code 2 is "Oxygen sensor circuit" that may be a complaint with the O2 sensor output.































This is a good time to replace the O2 sensor, if only because it is 14 years old and now there is a trouble code.































The lock-up solenoid is going to take some troubleshooting, but my guess is the solenoid itself is bad. They aren't a very high failure rate item but they have been known to fail.
