P2544 to P2555, P2637 to P2644 and P2512 to P2514: torque requests, inhibit and event data recorder
A torque management request or feedback signal (A or B) between the engine computer and another module is wrong, the throttle or fuel inhibit circuit has a fault, or the circuit that asks for an event data recording has a fault.
SeverityModerateUsually not urgent today, but it can get worse if left.
Can you keep driving?Drive gently, check it soonWhat does P2544 mean?
Other modules regularly ask the engine to change its torque: the gearbox to smooth a gear change, the stability control to stop a wheel spinning. On some cars these requests and the engine's feedback travel on dedicated wires rather than the network. The inhibit circuit lets another system block the throttle or fuel, for example an anti-theft module. The event data recorder request tells the airbag module to keep a record of a crash or near crash. Faults here can make gear changes harsh or stability control less effective.
What causes P2544?
- A damaged wire between the engine computer and the gearbox or ABS module
- A fault in the module sending the request, often with its own codes
- A corroded connector at either module
- An immobilizer or anti-theft fault, for the inhibit codes
What to check first for P2544
- Read the gearbox, ABS and airbag modules for related codes
- Inspect the connectors at the engine computer and the module named
- Note whether gear changes are harsh or the stability control light is on
- Check the battery and grounds, which affect every module
Can you drive with P2544?
Usually you can drive to a workshop. Gear changes may be harsher and traction or stability control may be off, so drive gently and leave more room in wet or slippery conditions.
In states with an OBD-II emissions inspection, a car with the check engine light on fails the test until the fault is fixed.
