P1715 - Shift Solenoid 2 Inductive Failure
The P1715 code indicates a malfunction in the inductive circuit of shift solenoid 2, which is responsible for controlling hydraulic pressure to engage specific gears in the automatic transmission. This solenoid uses an inductive (magnetic) signal to regulate fluid flow; when the powertrain control module (PCM) detects an open, short, or abnormal resistance in the solenoid's circuit, it sets this code. Common causes include a faulty solenoid, damaged wiring, or internal transmission issues.
01. Most Common Causes
- Faulty shift solenoid 2
- Damaged wiring or connector in solenoid circuit
- Low transmission fluid level or dirty fluid
- Internal transmission mechanical failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or delayed shifting
- Transmission stuck in limp mode or a single gear
- Decreased fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P1715 is present.
Step 2: Check transmission fluid level and condition; top off or replace if necessary.
Step 3: Inspect wiring and connector to shift solenoid 2 for damage, corrosion, or loose pins.
Step 4: Measure resistance of solenoid 2; compare to manufacturer specs (typically 20-40 ohms).
Step 5: If wiring and solenoid test OK, perform a transmission pressure test to rule out internal issues.

05. 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 further damage. Limp mode may limit speed.
How much does it cost to fix?▼
Repair costs range from $150 to $400, depending on whether the solenoid alone needs replacement or if wiring repairs are needed. Transmission rebuilds can cost more.
