P2545 means torque request A arrives intact but carries values the receiving module cannot accept as plausible – a requested torque outside the expected window, a request that contradicts the operating state, or one that does not follow up as it should. Ford's 2014 BOSS 302S engine module table lists P2545 with M, i.e. with check engine light. Jaguar Land Rover shows that the code can live in the transmission module as well: bulletin SSM73291 (2018) covers Discovery Sport from 2015MY and Range Rover Evoque from 2014MY with the ZF 9HP48 nine-speed, where the TCM logs P2545-86 and/or P2546-86; dealers should first fix oil leaks and level, then load newer TCM software, and escalate only if it returns. P2544 is the general signal fault, P2546 and P2547 low and high.

Likely causes

Transmission module software needs updating
Transmission oil leak or incorrect oil level (JLR 9HP48)
Requesting module sends implausible torque values

Symptoms

  • Check engine light (Ford) or transmission warning
  • Harsh or delayed shifts
