Shift Solenoid 1 Inductive Failure
The P1714 code indicates a malfunction in the inductive circuit of shift solenoid 1, which is responsible for controlling hydraulic pressure to engage specific gears in the automatic transmission. This solenoid operates using an electromagnetic coil that generates a magnetic field to move a valve; an inductive failure means the coil's electrical properties (inductance) are out of specification, often due to an open or short circuit, or excessive resistance. This can cause erratic shifting, harsh engagement, or transmission slippage.
1. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed gear shifts
- Transmission stuck in limp mode (e.g., 2nd gear)
- Poor fuel economy
2. Most Common Causes
- Faulty shift solenoid 1
- Damaged wiring or connector to solenoid
- Low transmission fluid level or contamination
- Internal transmission mechanical failure
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect transmission fluid level and condition; top off or replace if necessary.
Step 3: Visually check wiring and connectors to shift solenoid 1 for damage or corrosion.
Step 4: Measure solenoid resistance with a multimeter; compare to manufacturer specs (typically 10-30 ohms).
Step 5: If resistance is out of range, replace the solenoid; if in range, check for open/short in wiring or PCM issue.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the transmission may shift erratically or fail, potentially causing unsafe driving conditions. Limp mode may limit speed to 30-40 mph.
How much does it cost to fix?▼
The cost typically ranges from $150 to $400, including parts (solenoid $50-$150) and labor (1-2 hours at $100-$150/hour).
