P2787 — Clutch Temperature Too High

OBD2 code P2787 flags a problem with the sensor and actuator circuits (clutch temperature too high). The car is usually drivable while you plan the repair. Common culprits: poor ground connection, open or shorted wiring in the circuit, faulty sensor or actuator of the affected 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

Read the code and freeze frame Connect an OBD2 scanner, confirm P2787 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 clutch temperature too high for damage, corrosion, chafing or poor contact.
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 P2787 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2787 (parts and labor, USD, independent shop rates): Repair wiring or connectors: $80–$250; Replace the faulty sensor or actuator: $150–$500; Control module repair: $300–$1,000. Overall, fixing P2787 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

Will P2787 clear itself?

Sometimes P2787 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 are the symptoms of P2787?

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

What does OBD2 code P2787 mean?

What is the most common cause of P2787?

The most common causes are: poor ground connection, open or shorted wiring in the circuit, faulty sensor or actuator of the affected circuit.

How do I diagnose P2787 myself?

Start with a scan: confirm P2787, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the sensor and actuator circuits, and verify the suspect component against live data before buying parts.

What does P2787 mean?

P2787 is logged by the onboard diagnostics when the sensor and actuator circuits does not behave as expected. The official definition is “Clutch Temperature Too High”. This is a powertrain (engine/transmission) category code.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2787 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.
