What Does P2750 Mean?
The intermediate shaft speed sensor C is providing readings that are implausible or inconsistent with other transmission sensors. The TCM detects that sensor C output does not correlate properly with input/output shaft speeds or vehicle speed.
Common Causes
40%
Faulty intermediate shaft speed sensor C producing erratic signal
25%
Worn or damaged reluctor ring/tone wheel on intermediate shaft
20%
Internal transmission mechanical issues causing abnormal shaft speeds
10%
Excessive air gap between sensor and reluctor ring
5%
Intermittent wiring connection causing signal dropout
Diagnostic Steps
1
Step 1: Compare intermediate shaft speed sensor C readings to input and output speed sensor data in live data
2
Step 2: Inspect sensor mounting position and air gap to reluctor ring
3
Step 3: Check for metal debris on sensor tip indicating internal transmission wear
4
Step 4: Road test vehicle while monitoring all speed sensor inputs for correlation
5
Step 5: Perform transmission fluid inspection for contamination or metal particles
Estimated Repair Cost
$200 - $1,500
Parts + labor, varies by vehicle and location
The intermediate shaft speed sensor C is providing readings that are implausible or inconsistent with other transmission sensors. The TCM detects that sensor C output does not correlate properly with input/output shaft speeds or vehicle speed.
The most common cause of P2750 (Intermediate Shaft Speed Sensor C Circuit Range/Performance) is: Faulty intermediate shaft speed sensor C producing erratic signal
Typical repair costs for P2750 range from $200 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Transmission may shift erratically or unexpectedly. Vehicle may enter fail-safe mode with limited gear operation. Drive cautiously and seek repair soon.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2750 to identify the root cause.
