C0625 indicates that the Power Steering Control Module has detected a voltage or resistance reading from the Variable Effort Steering (VES) sensor that is outside its expected range, suggesting a problem with the sensor circuit or its inputs.
The sensor itself may have failed internally, producing out‑of‑range voltage signals.
Broken wires, poor connector contacts, or corrosion can cause resistance spikes that trigger the code.
Excessive friction or internal leaks can affect sensor output, leading to abnormal readings.
A weak power supply or bad ground to the module can cause erratic sensor data.
Very rarely, the control module itself may misinterpret correct sensor signals; this is the least likely cause.
Replacing the PCM is almost never necessary for C0625. The code most often results from a sensor, wiring, or mechanical issue; only after those are ruled out should a PCM replacement be considered.
The steering may still operate, but you can experience reduced assist, heavier steering effort, or intermittent loss of power steering, especially at low speeds.
Generally the vehicle remains drivable, but because power‑steering assist can be intermittent, exercise caution and have the issue diagnosed promptly.
Yes. After completing the repair, clear the code with a scan tool and verify that the condition does not return during a test drive.
