Mazda CX-5 Service & Repair Manual: Engine Control System

Outline

• L-jetronic*1 and D-jetronic*2 type detectors have been combined for intake air amount detection, improving the accuracy of the intake air amount measurement.

• MAF sensor adopted

• MAP sensor adopted

• IAT sensor No.1 and No.2 adopted

• Valve timing control has been adopted on both sides of the intake and exhaust, improving fuel economy and emission performance.

Intake side: Electric variable valve timing control

• Intake CMP sensor adopted

• Electric variable valve timing motor/driver adopted

• Electric variable valve timing relay adopted

Exhaust side: Hydraulic variable valve timing control

• Exhaust CMP sensor adopted

• Engine oil control has been adopted reducing engine load.

• Engine oil solenoid valve adopted

• With the adoption of fuel pump control, fuel pump power consumption has been reduced, improving fuel economy.

• Fuel pump control module adopted

• With the adoption of the ion sensor, which detects pre-ignition, engine reliability has been improved.

*2 Measures the intake air pressure introduced into the cylinder using the MAP sensor and calculates the intake air amount indirectly.
