Q: i have a 2005 ford f150 i washed my truck yesterday and about 15 minutes my truck just stopped working 2 codes cameup p2106 p0720

P0720 implicates the output speed sensor circuit. P2106 may have set as a consequence of the first code. Based on the codes, a suspicion is water intrusion in any of the wiring or terminals related to the speed sensor. That should be investigated and ruled out first. If you don’t see anything obvious accounting for the fault, you can request a check engine light diagnostic and a certified mechanic from YourMechanic will methodically test the appropriate individual vehicle components or sub-systems to pinpoint the underlying fault. If you have further questions or concerns, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you get the best possible results.
