This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with a sensor that helps control how the engine's valves open and close. It's like a teacher noticing a student not following instructions correctly.
The code indicates an issue with the Variable Valve Lift (VVL) reference sensor on Bank 2, which is not reading the expected values.
The P1070 code is triggered when the Engine Control Module (ECM) detects a discrepancy in the gradient of the VVL reference sensor signal on Bank 2. This sensor is crucial for monitoring the position and movement of the camshaft to adjust the valve lift for optimal engine performance.
• Check Engine Light is on
• Reduced engine performance
• Poor fuel economy
• Faulty VVL reference sensor
• Wiring issues or poor connections
• Malfunctioning ECM
VVL: Variable Valve Lift
ECM: Engine Control Module
• Use an OBD-II scanner to verify the code.
• Inspect the VVL reference sensor and its wiring for damage.
• Test the sensor's signal and compare it with manufacturer specifications.
• Replace the faulty VVL reference sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Nissan Maxima
• Infiniti G37
• Honda Accord
• Regular maintenance checks
• Ensure proper electrical connections
• Use quality replacement parts
Sensor Issue
• Do not ignore the Check Engine Light.
• Seek professional diagnostic services if unsure.
• Regularly maintain your vehicle to avoid such issues.
Check with the vehicle manufacturer for specific warranty coverage on sensors.
This code has been associated with vehicles using advanced VVL systems, particularly in models with higher mileage.
Moderate – While the vehicle may still operate, ignoring this code can lead to decreased performance and efficiency.
Driving with a malfunctioning engine sensor can lead to further damage and may not meet emissions standards.
• Engine at operating temperature
• Vehicle running at idle
The VVL reference sensor is typically located near the camshaft on Bank 2 of the engine.
Q: Can I drive with a P1070 code?
A: While you may be able to drive, it's not recommended as it can lead to poor performance and increased emissions.
Q: How can I prevent a P1070 code?
A: Regular maintenance and timely replacement of worn parts can help prevent this code.
