What P2A95 means
P2A95 says the module finds no proper current path through tank select valve B. Where a second select valve exists, it typically serves the next vessel or supply in line. Cespira's patent for a gas engine fed from two compressed-gas supplies shows how much depends on such valves: the controller connects each supply either to a compressor or to the regulator, and only by switching can it keep using a supply whose pressure has dropped. With valve B dead, that step is missing and fuel held in the affected vessel is effectively stranded. Unlike P2A22, which concerns the shutoff solenoid on tank B, this code concerns the routing valve. No manufacturer documents P2A95. A broken lead, a loose plug or an open coil are the usual findings.
P2A95 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2A95
- Malfunction lamp on
- Content of one vessel cannot be used
- Range well below the usual figure
Common causes of P2A95
- Most likelyLoose plug or broken wire to select valve B
- PossibleOpen solenoid coil of valve B
- Less likelyOutput stage for valve B in the module defective
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2A95 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. |
| 95 | The exact fault in that area. |
What to do next
- Note P2A95 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 P2A95
What does P2A95 mean?
P2A95 means "Alternative Fuel Tank Select Valve B Control Circuit/Open". P2A95 says the module finds no proper current path through tank select valve B. It is a generic code, so it means the same on every make.
Is it safe to drive with P2A95?
Drive gently and only to a workshop. With P2A95 the car can go into limp mode (reduced power) to protect itself.
Will P2A95 fail an emissions test?
Yes, it can. P2A95 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 P2A95 to fix?
Difficulty: hard. A typical repair takes 1 to 4 hours of work. This is a job for a workshop.
Will P2A95 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
