The P0970: Pressure Control Solenoid ‘C’ Control Circuit Low refers to an issue where the pressure control solenoid ‘C’ circuit is experiencing lower than expected voltage. This can result in improper operation of the solenoid, leading to poor regulation of transmission fluid pressure and affecting vehicle performance.
P0970 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0970: Pressure Control Solenoid ‘C’ Control Circuit Low |
| Is it serious? | Yes, low voltage can prevent proper transmission pressure control, causing shifting issues. |
| Possible causes | – Low voltage in the pressure control solenoid ‘C’ circuit – Faulty pressure control solenoid ‘C’ – Wiring or connector issues |
| How to diagnose? | – Check the circuit for low voltage – Inspect wiring and connectors – Replace the pressure control solenoid ‘C’ if necessary |
P0970 Meaning
The P0970: Pressure Control Solenoid ‘C’ Control Circuit Low code indicates that the voltage in the pressure control solenoid ‘C’ circuit is below the required level. This can prevent the solenoid from functioning properly, resulting in inadequate hydraulic pressure control in the transmission and shifting issues.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any additional fault codes that might provide further insight into the low voltage issue. | OBD-II Scanner |
| Test for Low Voltage | Use a multimeter to check the voltage in the pressure control solenoid ‘C’ circuit. Compare the readings with the manufacturer’s specifications to identify if the voltage is too low. | Multimeter |
| Inspect Wiring and Connectors | Inspect the wiring and connectors for signs of damage, corrosion, or loose connections that could cause low voltage in the solenoid circuit. | Flashlight, Multimeter |
| Test the Solenoid | Test the pressure control solenoid ‘C’ for proper operation. Replace the solenoid if it is faulty or not receiving adequate voltage. | Diagnostic Tool, Replacement Solenoid |
| Clear the Code and Test Drive | After completing repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | Re-scan the system to ensure the P0970 code does not reappear after the test drive. | OBD-II Scanner |
