Check Engine Light on with codes P1745, P0869, P0933 and P0934, transmission will not shift out of first gear?

These codes are all for the transmission pressure sensor or circuit. I have seen the TIPM go out on these vehicles which will cause this issue. Here is the location of the module. I would remove the electrical connectors and check them for water damage, overheated. I have included the transmission wiring diagrams so you can see how the system works.

The codes you provided are diagnostic trouble codes (DTCs) related to vehicle issues. Here's what each code represents:

P1745: This code indicates a problem with the transmission line pressure solenoid/pressure switch circuit. It typically points to an issue with the transmission system, such as a faulty solenoid or wiring problem. A malfunction in this component can result in various transmission issues, including harsh shifting, slipping, or failure to shift.

P0869: This code indicates a problem with the transmission fluid pressure. It is related to the line pressure sensor circuit. It typically points to an issue with the sensor itself or the associated wiring. Low or high fluid pressure can lead to transmission problems such as erratic shifting, slipping, or overheating.

P0933: This code indicates a problem with the hydraulic pressure sensor circuit in the transmission. It typically points to an issue with the sensor or its wiring. The hydraulic pressure sensor measures the fluid pressure inside the transmission and provides feedback to the vehicle's control module. A malfunction in this sensor can lead to various transmission issues and may result in the transmission going into a failsafe mode.

P0934: This code also relates to the hydraulic pressure sensor circuit, specifically indicating a problem with the sensor low. It means that the hydraulic pressure sensor is providing a low voltage signal or no signal at all. This can be caused by a faulty sensor, damaged wiring, or a problem with the transmission control module.

Let's check the m28, m33 and m15 fuses for power in the under-hood fuse panel (TIPM) The transmission control relay (on pcb) is not serviceable.
