I think the curious thing is that these codes set WHEN you were in the car wash. Most car washes aren't powerful or snaky enough to sling water on the TPS so not sure what is happening; it may be simply a coincidence. First thing I would do would be to disconnect the battery for 20 minutes or so, then start and drive the vehicle and see if the CEL comes back. If it doesn't, great. If it does, I would test the TPS, it's pretty easy to do. Use the SEARCH function for more information
