What Does P1916 Mean?
The high clutch drum speed sensor is providing incorrect or no signal to the transmission control module. This sensor monitors the rotational speed of internal transmission components to optimize shift timing and quality.
Common Causes
45%
Failed or damaged high clutch drum speed sensor
30%
Wiring harness damage, chafing, or connector corrosion between sensor and TCM
15%
Internal transmission mechanical damage affecting sensor reluctor ring or tone wheel
10%
Faulty transmission control module (TCM)
Diagnostic Steps
1
Step 1: Inspect transmission wiring harness and sensor connector for damage, corrosion, or loose connections
2
Step 2: Measure sensor resistance and compare to manufacturer specifications
3
Step 3: Check sensor signal voltage at TCM connector using a multimeter or oscilloscope while rotating input shaft
4
Step 4: Inspect transmission fluid level and condition for metal particles indicating internal damage
5
Step 5: If all external checks pass, internal transmission inspection may be required to examine reluctor ring and sensor mounting
Estimated Repair Cost
$200 - $1,500
Parts + labor, varies by vehicle and location
The high clutch drum speed sensor is providing incorrect or no signal to the transmission control module. This sensor monitors the rotational speed of internal transmission components to optimize shift timing and quality.
The most common cause of P1916 (High Clutch Drum Speed Sensor Malfunction) is: Failed or damaged high clutch drum speed sensor
Typical repair costs for P1916 range from $200 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience harsh or delayed shifting, reduced fuel economy, and potential transmission overheating. Continued driving could cause internal transmission damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1916 to identify the root cause.
