The PCM calculates input data and regulates transmission fluid pressure via a specially designed pressure control solenoid. The automatic transmission uses a high pressure pump (driven by the engine via the torque converter) to circulate fluid through the transmission hydraulic circuits in the transmission housing and valve body
This will help to determine whether or not the malfunction is intermittent. After the codes are cleared, test drive the vehicle to see if the code returns
If the initial resistance is within specifications, leave the leads of the digital volt/ohmmeter connected and heat the resistor with a heat gun
Should all system circuitry and sensors check out and the transmission is in good working order, suspect a faulty PCM but keep in mind that PCM failure is rare and PCM replacement will require reprogramming.
