P2750 — Intermediate Shaft Speed Sensor C Circuit Range/Performance

P2750 — Intermediate Shaft Speed Sensor C Circuit Range/Performance. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: control module driver fault, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.

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

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2750 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. 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.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the intermediate shaft speed sensor c for damage, corrosion, chafing or poor contact.
  4. Subsystem check Compare the intermediate shaft speed sensor c live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
  6. Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2750 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2750 (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 P2750 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 much does it cost to fix P2750?

Replace the faulty sensor or actuator — $150–$500; Control module repair — $300–$1,000; Repair wiring or connectors — $80–$250. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does OBD2 code P2750 mean?

P2750 — Intermediate Shaft Speed Sensor C Circuit Range/Performance. A fault in the sensor and actuator circuits. The car is usually drivable while you plan the repair. Typical causes: control module driver fault, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.

How do I diagnose P2750 myself?

Start with a scan: confirm P2750, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the intermediate shaft speed sensor c, and verify the suspect component against live data before buying parts.

What are the symptoms of P2750?

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

What is the most common cause of P2750?

The most common causes are: control module driver fault, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.

What does P2750 mean?

Behind P2750 is a specific failure in the sensor and actuator circuits: intermediate shaft speed sensor c circuit range/performance. The onboard computer stores it in the powertrain (engine/transmission) group after verifying the fault over repeated checks.

“Range/performance” means the signal from the intermediate shaft speed sensor c is electrically valid but does not match what the module expects for current operating conditions. The wiring is usually intact; the problem is a degraded component, a drifted sensor or a mechanical fault upstream.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2750 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes P2750?

  • degraded or drifting intermediate shaft speed sensor c
  • incorrect calibration after a module update or battery disconnect
  • mechanical fault that the sensor correctly reports
  • open or shorted wiring in the circuit
  • faulty sensor or actuator of the affected circuit
  • corroded, loose or damaged connector
  • poor ground connection
  • control module driver fault
  • blown fuse feeding the circuit

Common symptoms of P2750

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

How to diagnose P2750

  1. Connect an OBD2 scanner, confirm P2750 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. 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.
  3. Visually inspect the wiring harness and connectors related to the intermediate shaft speed sensor c for damage, corrosion, chafing or poor contact.
  4. Compare the intermediate shaft speed sensor c live reading against a known-good reference (specification or a correlated sensor) under the conditions from the freeze frame.
  5. Measure reference voltage, ground and signal continuity at the component connector.
  6. Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  7. Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2750 does not return.
