What P0745 means
Pressure control solenoid A sets line or clutch pressure by current; most are 'normally high', so with no current – as in limp mode – maximum pressure applies. 'A' is usually the line pressure valve, on GM clutch-to-clutch transmissions (6T, 8L, 9T) the pressure valve of clutch 1. Ford does not use P0745–P0749 but P0960–P0963. P0745 is the general code for this valve; the sub-codes P0746–P0749 follow. It is documented on Mitsubishi CVTs as a current plausibility check: at most 400 mA while 750 mA or more is commanded for 5 s, or 1.34 A or more for 1 s. A failure usually leaves the valve unpowered, so pressure goes to maximum: harsh shifts and, depending on the transmission, limp mode in a fixed gear.

Symptoms of P0745
- Harsh shifts or engagement (maximum pressure)
- Limp mode in a fixed gear
- Transmission warning or check engine light
Common causes of P0745
- Most likelyPressure control solenoid (coil) faulty
- Most likelyTransmission harness or connector
- PossibleContaminated fluid, valve sluggish
- Less likelyTransmission module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0745 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 45 | The exact fault in that area. |
What to do next
- Note P0745 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 P0745
What does P0745 mean?
P0745 means "Pressure Control Solenoid A". Pressure control solenoid A sets line or clutch pressure by current; most are 'normally high', so with no current – as in limp mode – maximum pressure applies. It is a generic code, so it means the same on every make.
Is it safe to drive with P0745?
Drive gently and only to a workshop. With P0745 the car can go into limp mode (reduced power) to protect itself.
Will P0745 fail an emissions test?
Yes, it can. P0745 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 P0745 to fix?
Difficulty: medium. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0745 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.
