So a few months ago I had to change TB due to codes about TB switch low circuit. Then hell broke loose. I have now about seven codes but the most important one is how the hell do I fix the p0652 which is causing mountain of issues. Car not starting battery drains like a fountain, so I can't get the right wiring for the TB, crankshaft camshaft n even the map n intake te n oil pressure sensor. This has me running in circles spending more thank I can save with doordash n delivery jobs I have now. Can't even drive to work to get ahead. How do I fix this pls. I have most pins registering low or high voltage. And more than one pin giving out 5v. Thru out the connectors. What do I do pls

If this problem happened right after you changed the throttle body I would remove it and swap it out for another, it sounds like you got a defective unit. One shorted sensor can drag down the whole 5 V “B” bus and cause a bunch of weird codes including throttle and cam-crank plausibility faults.

P0652 - Sensor reference voltage “B” low

P0016 - Crankshaft/Camshaft correlation (Bank 1 Sensor A)

P0013 - Camshaft position actuator “B” control circuit (Bank 1) - exhaust side

P0123 - Throttle/Pedal position sensor “A” circuit high

So if the TB is shorted you can see it will cause these issues. Also to be sure you can disconnect the TB and see if the 5 volt reference returns. Please let me know how it goes.
