This summary uses the existing diagnostic information shown in full below.
This code means the car's computer found a problem with how the gas pedal and the air going into the engine are working together. It's like when you press the gas pedal and the car doesn't speed up like it should.
The code indicates a discrepancy between the throttle position sensor and the hot film air mass meter readings, suggesting a possible issue with how these components are interacting.
P1162 is triggered when the engine control module (ECM) detects a mismatch between the expected values from the Throttle Position Sensor 2 and the Hot Film Air Mass Meter on Bank 1. This could indicate a fault in either sensor or in the communication between them.
• Check Engine Light illuminated
• Poor acceleration
• Engine stalling or hesitation
• Faulty Throttle Position Sensor 2
• Defective Hot Film Air Mass Meter
• Wiring issues or poor connections
Throttle Position Sensor: A sensor that monitors the position of the throttle in the engine.
Hot Film Air Mass Meter: A device that measures the amount of air entering the engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for both sensors.
• Test the sensors for proper operation.
• Replace the Throttle Position Sensor 2 if faulty.
• Replace the Hot Film Air Mass Meter if defective.
• Repair any damaged wiring or connections.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford Focus
• Honda Accord
• Toyota Camry
• Regular maintenance and sensor checks
• Ensure clean air filters
• Avoid driving in extreme conditions without proper checks
Sensor Issue
• Do not ignore the check engine light.
• Get the vehicle inspected by a professional if unsure.
• Regularly check and maintain sensor connections.
Check with your vehicle manufacturer for specific warranty coverage on sensors.
This code has been more prevalent in vehicles with higher mileage where sensor wear is common.
Moderate – Addressing this issue can prevent further engine performance problems.
Driving with a faulty sensor can lead to reduced engine performance and increased emissions.
• Engine at operating temperature
• Vehicle in idle and acceleration states
The Throttle Position Sensor is located on the throttle body, and the Hot Film Air Mass Meter is typically near the air intake system.
Q: Can I drive with a P1162 code?
A: It's possible, but not recommended as it can lead to poor engine performance.
Q: How do I reset the check engine light after fixing the issue?
A: Use an OBD-II scanner to clear the code after repairs are completed.
