P2730Pressure Control Solenoid E Control Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2730 is stored when the control line of solenoid E sits too high, pointing to contact with a supply voltage. GM's Allison 1000 logic looks for a power short at the PCS 1 output and treats it as Type A. Its 2016 six-speed tables word the code as circuit high for an open or a power short, so there a broken wire may show up as P2730 instead of P2727. The 2023 Corvette dual-clutch TCM switches the driver on and compares the sense voltage with a limit that depends on supply, about 0.7 V at low and 1.1 V at high battery voltage (Type A); Ford's TR9070 calls the same fault shorted load. No public bulletin links P2730 to a particular repair, so standard tracing of harness, connector and solenoid applies.
- What you may notice
- MIL on and transmission in fail-safe
- Harsh or missing shifts
- Code sets again immediately after clearing
- Likely causes
- LikelyControl wire chafed against a supply circuit
- PossibleOpen line on units that report it as high (GM six-speed)
- PossibleDefective solenoid E
- RareTCM driver fault
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
