What P2752 means
P2752 flags a sensor C circuit that cuts out now and then, briefly enough that neither the circuit code P2749 nor the no-signal code P2751 matures. No manufacturer documents P2752 publicly. The closest published counterpart is Ford's P2748 for sensor B on its ten-speed automatics, an intermittent check that runs continuously beside the circuit and plausibility tests. CARB expects every such transmission input to be monitored for circuit faults. In practice the culprit is mechanical stress on the wiring: a terminal that loosens when hot, insulation worn through on a bracket, or water that wicks into the plug. Watching sensor C while flexing the harness, and reading the freeze frame, are the most useful steps.
P2752 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P2752
- Sporadic warning lamp
- Occasional rough shift
Common causes of P2752
- Most likelyTerminal losing contact when hot
- PossibleInsulation worn through at a bracket or edge
- PossibleWater ingress into the connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2752 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 52 | The exact fault in that area. |
What to do next
- Note P2752 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 P2752
What does P2752 mean?
P2752 means "Intermediate Shaft Speed Sensor C Circuit Intermittent". P2752 flags a sensor C circuit that cuts out now and then, briefly enough that neither the circuit code P2749 nor the no-signal code P2751 matures. It is a generic code, so it means the same on every make.
Is it safe to drive with P2752?
Drive gently and only to a workshop. With P2752 the car can go into limp mode (reduced power) to protect itself.
Will P2752 fail an emissions test?
Yes, it can. P2752 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 P2752 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2752 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.
