P2A30Alternative Fuel Tank Shutoff Valve E Control Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- 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.
