What does trouble code p0758 mean on a Chevy?
What does trouble code p0758 mean on a Chevy?
Troubleshooting and solving a trouble code P0758 usually involves replacing the 2-3 shift solenoid. Before buying and replacing the shift solenoid, I recommend that you test it to make sure its bad. Testing the solenoid’s internal resistance (specification: 19-31 Ohms). Checking its electrical connector for damage.
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:
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.
What is the purpose of a shift solenoid?
If you have an Overdrive or other transmission warning lamp, it may be illuminated also. The purpose of the Shift Solenoid Circuit is for the PCM to monitor the shift solenoids to manage the movement of fluid between various hydraulic circuits and change the transmission gear ratio at the appropriate time.
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 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 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.
What causes a PCM to record a p0758 code?
A number of issues can cause the PCM to record a P0758 code, including: 1 Shift solenoid B is faulty. 2 The wiring or connector for shift solenoid B is loose, shorted, or open. 3 The valve body is defective. 4 The transmission fluid is low and/or contaminated.
