P2A64Alternative Fuel Tank C Level Sensor Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- A third gas tank, C, may have its own level input, either a real float sender in an LPG vessel or, on CNG, a value the module derives from that tank's pressure, the way Ford's 2003 bi-fuel trucks turned tank pressure into a gauge reading. P2A64 reports that the tank C level circuit is faulty without saying whether the signal is too low or too high; P2A66 and P2A67 make that distinction. Even the petrol-based code set ends at a second sender, so there is no conventional analogue for a third tank, and no manufacturer documents P2A64. The effect is mostly informational: the gauge or range shown may leave out tank C. Inspect the sender plug and its wiring run, which on rear-mounted tanks is often long and exposed.
- What you may notice
- Check engine light
- Gauge or range leaves out tank C
- Otherwise normal driving
- Likely causes
- LikelyLong harness run to tank C damaged or plug loose
- PossibleTank C sender defective
- RareFault in the tank C pressure input the level is derived from (CNG)
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
