P0940 OBD-II: Hydraulic Oil Temperature Sensor Circuit High
P0940 Severity
Will P0940 go away on its own?
Once the vehicle's onboard system no longer detects the issue, most codes will disappear on their own. If your vehicle still has this code, however, it should be properly diagnosed to avoid a more serious problem.
For a proper diagnosis, RepairPal Certified shops have the equipment, tools, and expertise.
Moderate severity codes might not threaten the vehicle's safety or functionality immediately, but you should still get it diagnosed within a reasonable time frame to keep your car running well.
What causes OBD-II fault code P0940?
The clutch uses hydraulic pressure to engage and disengage the clutch as well as shift gears. The Hydraulic Oil Temperature Sensor tells the Transmission Control Module (TCM) the temperature of the system. If the sensor sends back an implausible signal, code P0940 is stored.
