P07F5 code meaning
Transmission Range Control Module System Voltage Low
What P07F5 means
The transmission range control module is the separate shift-by-wire control unit that reads the selector and drives the range actuator. P07F5 means its supply voltage is too low. No manufacturer document available to us uses the generic code, but GM checks exactly this under its own P17B0: battery voltage at the range control module at or below 9 V for 5 s within a 6 s window, type C without MIL. With too little voltage the actuator may not set the range or park pawl reliably; GM also suspends further checks of the module. A weak battery or a resistance in the module's fuse, supply or ground is the usual cause.
P07F5 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyEasy, DIY possible
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P07F5
- Shift warning
- Range or park lock reacts late or not at all
- Often together with battery voltage codes
Common causes of P07F5
- Most likelyWeak battery or charging system
- PossibleFuse, supply or ground wire of the module with high resistance
- Less likelyHigh actuator motor current on a weak supply
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P07F5 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. |
| F5 | The exact fault in that area. |
What to do next
- Note P07F5 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 P07F5
What does P07F5 mean?
P07F5 means "Transmission Range Control Module System Voltage Low". The transmission range control module is the separate shift-by-wire control unit that reads the selector and drives the range actuator. It is a generic code, so it means the same on every make.
Is it safe to drive with P07F5?
Drive gently and only to a workshop. With P07F5 the car can go into limp mode (reduced power) to protect itself.
Will P07F5 fail an emissions test?
P07F5 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 P07F5 to fix?
Difficulty: easy. A typical repair takes 0.3 to 1.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P07F5 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
