P1714 - Shift Solenoid 1 Inductive Failure
The P1714 code indicates a problem with the inductive circuit of shift solenoid 1 in the automatic transmission. This solenoid controls hydraulic pressure for gear shifting. The transmission control module (TCM) detects an electrical fault, such as high resistance, short, or open circuit in the solenoid coil. This can cause harsh shifts, slipping, or failure to shift.
01. Most Common Causes
- Faulty shift solenoid 1
- Wiring or connector damage in solenoid circuit
- Low transmission fluid level or contamination
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light on
- Harsh or erratic shifting
- Transmission slipping or stuck in gear
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition.
Step 3: Test solenoid resistance with multimeter (specs: 10-30 ohms).
Step 4: Check wiring and connectors for damage or corrosion.
Step 5: Perform solenoid power/ground test using a scan tool or test light.
