P2767 — Input/Turbine Speed Sensor "B" Circuit No Signal

powertrain (engine/transmission)

Is it safe to drive?

Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

How to diagnose with an OBD scanner

Read the code and freeze frame Connect an OBD2 scanner, confirm P2767 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the input/turbine speed sensor "B" circuit for damage, corrosion, chafing or poor contact.
Subsystem check Verify power and ground directly at the input/turbine speed sensor "B" circuit connector with a multimeter before touching the signal side.
Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2767 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2767 (parts and labor, USD, independent shop rates): Replace the faulty sensor or actuator: $150–$500; Control module repair: $300–$1,000; Repair wiring or connectors: $80–$250. Overall, fixing P2767 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

How do I diagnose P2767 myself?

Start with a scan: confirm P2767, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the input/turbine speed sensor "B" circuit, and verify the suspect component against live data before buying parts.

Will P2767 clear itself?

Sometimes P2767 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What is the most common cause of P2767?

The most common causes are: faulty sensor or actuator of the affected circuit, blown fuse feeding the circuit, open or shorted wiring in the circuit.

What are the symptoms of P2767?

Drivers most often notice: increased fuel consumption in some cases, the affected system operates intermittently or not at all, Check Engine Light on, possible limp mode depending on the affected component.

What does OBD2 code P2767 mean?

Input/Turbine Speed Sensor "B" Circuit No Signal (P2767): a powertrain (engine/transmission) fault affecting the sensor and actuator circuits. The car is usually drivable while you plan the repair. Most often caused by faulty sensor or actuator of the affected circuit, blown fuse feeding the circuit, open or shorted wiring in the circuit.

What does P2767 mean?

P2767 (Input/Turbine Speed Sensor "B" Circuit No Signal) is stored when self-diagnostics detect abnormal readings or behaviour of the sensor and actuator circuits. It belongs to the powertrain (engine/transmission) category.

“No signal” or “invalid data” means the module receives nothing usable from the input/turbine speed sensor "B" circuit — as if it were not connected at all. Check power and ground of the component before suspecting the signal wire: a dead component produces the same code.

To set P2767, the control module compares live readings of the sensor and actuator circuits against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.

What causes P2767?

completely failed input/turbine speed sensor "B" circuit
open signal wire or connector
no power or ground at the input/turbine speed sensor "B" circuit
open or shorted wiring in the circuit
faulty sensor or actuator of the affected circuit
blown fuse feeding the circuit
corroded, loose or damaged connector
control module driver fault

Common symptoms of P2767

increased fuel consumption in some cases
the affected system operates intermittently or not at all
Check Engine Light on
possible limp mode depending on the affected component

How to fix P2767

Start with the cheapest and most common causes before replacing expensive parts:

Replace the faulty sensor or actuator — $150–$500
Control module repair — $300–$1,000
Repair wiring or connectors — $80–$250

How much does it cost to fix P2767?

Repair cost depends on which component actually failed. Typical scenarios for P2767 (parts and labor, USD, independent shop rates):

Can you drive with P2767?

In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.
