- How the car detects it
- P07B5 means something different at each manufacturer. At GM it covers the P button of the shift-by-wire selector: sensor A reads in the band between its 'released' and 'pressed' zones (53.2–73.7 % of 5 V, ICCM 45–58 %), after two trips. On the Chrysler Pacifica plug-in hybrid it is the park pawl position sensor 1 in the transmission, fixed by software together with park actuator codes. On the 2017–18 Genesis G80/G90 it reads 'park position sensor circuit low' and the park position switch is replaced. In all cases the module cannot reliably determine the park request or position.
