What does P0758 Mean? The PCM has detected an abnormality in shift solenoid B. The computer controlled automatic transmission uses shift solenoids to manage the transfer of fluid between hydraulic circuits and actuate a change in transmission gear ratio. Varying gear ratios are needed to increase and decrease vehicle speed, maximize engine performance, and optimize fuel efficiency. engine code P0758P0758 fixobd P0758dtc P0758obd code P0758obd2 P0758P0758 car codediagnostic code P0758car code P0758check engine code P0758fehlercode P0758P0758 fiatcodigo P0758codigo falla P0758P0758 kody b??dówcodigo de falla P0758 What are the common causes of P0758 ? A number of issues can cause the PCM to record a P0758 code, including: Shift solenoid B is faulty. The wiring or connector for shift solenoid B is loose, shorted, or open. The valve body is defective. The transmission fluid is low and/or contaminated. How do you troubleshoot P0758 ? While fuel economy was increased, acceleration was seriously compromised, and the loss of engine vacuum led to a dangerous loss of braking assist when the P0758 code system was in four-cylinder mode. In addition to these issues, while the company proposed a hydraulically controlled system that could be switched from within the car, the version they implemented had to be manually changed in the engine compartment using hand tools.
