How does an electronic shift solenoid operate?
How Do Transmission Solenoids Work? Transmission solenoids have a spring-loaded plunger inside, which is wrapped in a wire connected to the speed sensors and ECU or TCM. That wire is how they receive signals to adjust the flow of hydraulic fluid within the transmission.
What causes Shift Solenoid B to record a p0758 code?
If the PCM records code P0758, it indicates that the PCM cannot see the proper change in engine RPMs or the correct increase in road speed that should be happening during a shift from second to third gear. What causes the P0758 code? A number of issues can cause the PCM to record a P0758 code, including: Shift solenoid B is faulty.
What is an OBD code for shift solenoids?
In this case, the P0758 OBD-II trouble code is associated with a an electrical malfunction with the the transmission Shift Solenoid “B” Circuit. Example of shift solenoids:
When is the p0758 code detected on a car?
When is the P0758 code detected? The P0758 code is detected when the gear required by the ECM does not match the actual gear when vehicle is driven. Engine Light ON (or Service Engine Soon Warning Light)
What are the trouble codes for the B solenoid?
The trouble codes related to this, the “B” solenoid, are codes P0755, P0756, P0757, P0758 and P0759 based on the specific malfunction that alerts the PCM to set the code and illuminate the Check Engine Light. These codes will also be associated to the A, B or C solenoid circuit.
If the PCM records code P0758, it indicates that the PCM cannot see the proper change in engine RPMs or the correct increase in road speed that should be happening during a shift from second to third gear. What causes the P0758 code? A number of issues can cause the PCM to record a P0758 code, including: Shift solenoid B is faulty.
In this case, the P0758 OBD-II trouble code is associated with a an electrical malfunction with the the transmission Shift Solenoid “B” Circuit. Example of shift solenoids:
What are the possible causes of a p0758 Chevrolet?
P0758 Chevrolet Possible Causes. Low transmission fluid level. Dirty transmission fluid. Faulty 2-3 Shift Solenoid Valve. 2-3 Shift Solenoid Valve harness or connectors. 2-3 Shift Solenoid Valve circuit is open or shorted.
What does DTC p0758 mean in Powertrain Control Module?
When the Powertrain Control Module (PCM) detects a continuous open, short to ground or short to power in the 2-3 Shift Solenoid (SS) valve circuit, then DTC P0758 sets. The 2-3 Shift Solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves.
