P2752
Intermediate Shaft Speed Sensor C Circuit Intermittent
Transmission (speed sensor)
Generic OBD-II
Medium
What it means
P2752 means the intermediate shaft speed sensor signal is cutting out intermittently. The transmission uses this sensor to monitor gear ratios and time shifts, so a dropping signal can cause erratic or harsh shifts and brief limp-mode events. The usual culprits are a loose connector, debris on the sensor, or a failing sensor — the car stays drivable while you track it down.

Can I keep driving? Drivable, but the intermittent signal can cause erratic or harsh shifts and brief limp-mode events.

How to diagnose & fix
Work through it in order
- Read freeze-frame data to catch the conditions when it set.
- Wiggle-test the connector and wiring to reproduce the dropout.
- Inspect the sensor tip and reluctor for debris or damage.
- Check the sensor air gap where adjustable.
- Replace the sensor if faulty. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2752?+
Usually short-term. The intermittent signal can trigger erratic shifts or brief limp mode, so have it diagnosed before it becomes constant.
Can I just clear P2752?+
Intermittent faults return once the dropout recurs. Finding and fixing the loose connection or sensor is what holds.
