What P2A30 means
P2A30 sets when the control circuit of shutoff valve E reads low. TransEco Energy's AFCM v1.4 table names a short to ground or an open lead as the reason and keeps both dedicated and bi-fuel vehicles running, MIL on; P2A20 is listed beside it. Ford's Boss 302S code list contains P2A30 as well. A low reading on valve E alone points to the branch of the harness serving that cylinder. If B to E show low faults together, a shared ground or a connector close to the module is the more likely culprit. Tanks of this kind hold gas at up to about 24,800 kPa, so only trained staff should open any part of the system. P2A31 is the matching high fault, P2A2E the open circuit.
P2A30 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2A30
- Check engine light
- Gas from tank E not usable
Common causes of P2A30
- Most likelyControl lead of valve E touching ground
- PossibleShared ground or connector near the module (several low codes together)
- Less likelyShorted coil in valve E
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2A30 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| A | Area: hybrid propulsion. |
| 30 | The exact fault in that area. |
What to do next
- Note P2A30 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 P2A30
What does P2A30 mean?
P2A30 means "Alternative Fuel Tank Shutoff Valve E Control Circuit Low". P2A30 sets when the control circuit of shutoff valve E reads low. It is a generic code, so it means the same on every make.
Is it safe to drive with P2A30?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2A30 fail an emissions test?
Yes, it can. P2A30 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2A30 to fix?
Difficulty: hard. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2A30 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
