P1835

What the Code Means

Code P1835 indicates that the transmission control unit (TCU) has flagged a high signal from the pressure control solenoid valve E. This valve regulates hydraulic pressure for clutch engagement. A high signal can point to a short to power or a fault in the valve itself.

Symptoms

• Harsh shifts
• Transmission slip
• Delayed engagement
• Check Engine light on (malfunction indicator)

Symptoms can appear in any driving mode, especially under acceleration.

Diagnosis and Repair

Step 1: Check Valve Resistance

• Measure the resistance of solenoid valve E with a multimeter. Normal value: 4–6 ohms.
• If resistance is out of range, the valve is faulty.

Step 2: Check Wiring and Connector

• Inspect the wiring harness and valve connector for a short to power or damage.
• Check insulation integrity.

Step 3: Replace the Valve

• If faulty, replace the valve with an OEM unit (24001442383).

Step 4: Clear Codes and Test Drive

• After repair, clear the fault codes and take a test drive to verify.

Common diagnostic mistake: replacing the valve without checking the wiring — the problem is often a short, not the valve itself.

Secondary Damage

Ignoring code P1835 can lead to:

• Clutch slip from incorrect pressure
• Transmission overheating
• Complete transmission failure (expensive repair or replacement)

Severity: high. Immediate diagnosis is recommended when symptoms appear.
