P2767 - Input/Turbine Speed Sensor Circuit No Signal
The P2767 code indicates that the Powertrain Control Module (PCM) has detected no signal from the input/turbine speed sensor, which monitors the rotational speed of the transmission's input shaft. This sensor is critical for proper transmission operation, including shift timing and torque converter lockup. A loss of signal can result from a faulty sensor, damaged wiring, or internal transmission issues.
01. Most Common Causes
- Faulty input/turbine speed sensor
- Damaged or corroded wiring/connectors
- Low transmission fluid level
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Erratic or harsh shifting
- Transmission stuck in limp mode
- Poor acceleration or no forward/reverse
03. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P2767 is present.
Step 2: Inspect transmission fluid level and condition.
Step 3: Visually check sensor wiring and connector for damage or corrosion.
Step 4: Test sensor resistance and signal output with a multimeter.
Step 5: If sensor and wiring are good, inspect transmission for internal damage.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, driving with P2767 can cause severe transmission damage. The vehicle may enter limp mode, limiting speed and causing unsafe driving conditions.
How much does it cost to fix?▼
Repair costs range from $150 to $400, depending on the cause. A sensor replacement is typically $150-$250, while wiring repairs or internal transmission work can be higher.
