Throwing a P0122 code. Losing throttle response. Hlp.
Hey guys! Throwing that code and also losing throttle response at about 3k rpms. It’ll frequently go past it but will lose throttle response again almost immediately. I installed an aem 3.5 bar map sensor before this happened. Worked fine, threw a map code but didn’t have issues until recently. The car runs fine when I unplug the map sensor. I would just have to grandpa it.
Any ideas?

Heres a thread where the same TPS code was thrown but was a faulty MAP sensor

Is that a new sensor you installed? Can you load the old sensor back in & check that?

Forgot to add, When I was messing with the AEM EMS ecu at full open throttle my tps was at like 3.0 volts. Think they’re supposed to be at 5 V?
