Tps shorted on dodge pickups

this is an obd2 trouble code table, it can help you understand the meaning of code.
for p0120,
the possible solutions:
If you have access to a scan tool, with KOEO (Key on engine off) observe the TPS voltage. With throttle closed, voltage should be about .45 volts. It should gradually sweep upwards to approximately 4.5 to 5 volts as you depress the throttle. Sometimes only a scope can capture an intermittent glitch in the TPS signal voltage. If you notice a glitch in the TPS sweep voltage, replace the TPS.
NOTE: Some TPS sensors require fine adjustment. If you aren't comfortable with using a DVOM (Digital Volt Ohm meter) to adjust the new TPS, then it's best to take the vehicle to a shop. If the voltage is not .45 volts (+or- .3 volts or so) with the throttle closed or if the reading is "stuck" then unplug the TPS connector. With KOEO check for 5 volts reference voltage present at the connector and a good ground. You can check the signal circuit for continuity by jumping a fused wire between the ground circuit of the TPS connector and the signal circuit. If the TPS reading on the scan tool now reads zero, then replace the TPS. However if that doesn't change the reading to zero, then check for an open or a short on the signal wire and if none is found, suspect a bad PCM. If manipulating the TPS wiring harness causes any change in idle, then suspect bad TPS.

????1762 should be a transmission problem!!! Makes no sense at all.
Review: you had a tps code (but the engine ran well?) You changed it and it threw injector codes and ran poorly...You took it out and put the old one back (was code still there? Did it run well?) You put another new one in and now you have a transmission code? and how is it running?
Only commonality here is that the tps runs in tandem with all other sensors Make sure you clear old codes after doing any work and see what comes up after driving through a few cycles/ And get a volt/ohm meter and test the tps to see if in fact it's out of range. It somehow sounds more like a MAP sensor problem..or even a harness problem....but, test before getting anything else.

check the wires to the fuel pump if they have rubbed against something and the insulation wore through hitting bumps or rain could cause it to short and kick the relay and resets again and will start

the expeditions had a problem with the rear wiper motor grounding out, i would try replacing the wiper motor first, as for the fuse blowing, it is blowing for a reason, fuses don't just blow. if the wiper motor does not fix you may need to have someone go thru the electrical pin point tests to find the short.

If it happens only when it rains it means that water or moisture is getting under the distributor. The distributor needs to be replaced. Good Luck. Let me know how it turns out.
