What P07B5 means
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.
P07B5 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P07B5
- Check engine light, 'service transmission' or 'unable to shift' message
- Park cannot be selected by button, or the car will not shift out of P
- P button illumination off
Common causes of P07B5
- Most likelyP button sensor faulty or worn
- PossibleKnob not seated, button sticking
- PossibleContact resistance in the connector
- Less likelyModule software
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P07B5 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| B5 | The exact fault in that area. |
What to do next
- Note P07B5 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P07B5
What does P07B5 mean?
P07B5 means "Transmission Park Position Sensor/Switch A Circuit Performance/Low". P07B5 means something different at each manufacturer. It is a generic code, so it means the same on every make.
Is it safe to drive with P07B5?
Drive gently and only to a workshop. With P07B5 the car can go into limp mode (reduced power) to protect itself.
Will P07B5 fail an emissions test?
P07B5 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P07B5 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P07B5 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
