Shift Solenoid 'E' Control Circuit High
The P0983 code indicates that the Powertrain Control Module (PCM) has detected a high voltage condition in the control circuit of shift solenoid 'E'. This solenoid is responsible for directing hydraulic fluid to engage specific gears in the automatic transmission. A high voltage reading typically points to a short to power, a faulty solenoid, or an internal PCM issue. This can cause harsh shifting, gear slippage, or transmission stuck in a single gear.
01. Most Common Causes
- Short to power in the solenoid control circuit
- Faulty shift solenoid 'E'
- Damaged wiring or connector
- Internal PCM failure
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Harsh or erratic shifting
- Transmission stuck in gear
- Decreased fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and record freeze frame data.
Step 2: Visually inspect wiring and connectors for damage, corrosion, or shorts.
Step 3: Test solenoid resistance with a multimeter; compare to manufacturer specs.
Step 4: Check for power and ground at solenoid connector with key on.
Step 5: If wiring and solenoid are okay, test PCM output or replace PCM.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended. Driving with a high voltage solenoid circuit can cause transmission damage or sudden failure. Have it diagnosed promptly.
How much does it cost to fix?▼
Repair costs range from $150 to $400, depending on whether it's a wiring repair, solenoid replacement, or PCM replacement.
