What P2545 means
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.
P2545 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P2545
- Check engine light (Ford) or transmission warning
- Harsh or delayed shifts
Common causes of P2545
- Most likelyTransmission module software needs updating
- PossibleTransmission oil leak or incorrect oil level (JLR 9HP48)
- Less likelyRequesting module sends implausible torque values
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2545 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 45 | The exact fault in that area. |
What to do next
- Note P2545 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2545
What does P2545 mean?
P2545 means "Torque Management Request Input Signal A Range/Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P2545?
Drive gently and only to a workshop. With P2545 the car can go into limp mode (reduced power) to protect itself.
Will P2545 fail an emissions test?
Yes, it can. P2545 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2545 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2545 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
