This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has noticed a problem with how the engine is idling. It's like when you're trying to keep a toy spinning at a certain speed, but it keeps going too fast or too slow.
The code indicates a discrepancy between the actual and desired idle speed control valve positions for Bank 2 of the engine.
P153E is triggered when the Engine Control Module (ECM) detects that the actual position of the idle speed control valve does not match the desired position for Bank 2. This can affect the engine's ability to maintain a stable idle speed.
• Engine idles erratically
• Check Engine Light is on
• Poor engine performance at idle
• Faulty idle speed control valve
• Wiring issues or poor electrical connections
• Vacuum leaks in the intake system
Idle Speed Control Valve: A component that regulates the engine's idle speed.
ECM: Engine Control Module, the computer that manages engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the idle speed control valve and related wiring.
• Check for vacuum leaks in the intake system.
• Replace the idle speed control valve if faulty.
• Repair or replace damaged wiring or connectors.
• Fix any vacuum leaks found in the intake system.
• OBD-II scanner
• Multimeter
• Vacuum leak detector

Engine Performance
• Address this issue promptly to avoid stalling.
• Have a professional mechanic inspect the vehicle if unsure.
Check with the vehicle manufacturer for specific warranty coverage on engine components.
This code is commonly associated with European vehicles and typically points to issues with the idle control system.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with an unresolved idle control issue can lead to stalling, which may be dangerous in traffic.
• Engine at operating temperature
• Vehicle in idle state
The idle speed control valve is typically located on the throttle body of the engine.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to poor engine performance and potential stalling.
Q: Can I drive my car with this code?
A: It's possible, but not recommended as it may lead to unsafe driving conditions.
