Mazda CX-5 Service & Repair Manual: Electronic Control System Outline [Fw6 A EL, Fw6 Ax EL]
Outline
-
In the electronic control system, the TCM calculates the control content based on signals from each type of sensor and switch to operate output parts such as each solenoid. In consideration of suppressed shift shock, smooth driving, and improved fuel economy, the TCM performs controls so as to maintain the optimum driving performance in response to the vehicles driving scenario.

Electric Variable Valve Timing Control
Outline
The PCM determines the optimum intake valve timing according to the engine
operation conditions, and sends the motor drive signals to the electric variable
valve timing driver. Wi ...

Shift Pressure Control (Direct Electric Shift Control) [Fw6 A EL, Fw6 Ax EL]
Outline
The TCM drives shift solenoids No.1, 2, 3, 4, the pressure control solenoid,
and the on/off solenoid based on inputs signals from each switch and sensor,
and performs direct electronic control of the clutch engagement pressure. As
a result, precise hydraulic pressure control ...
Oil Filter
Purpose, Function
Engine oil is filtered by passing engine oil through the oil filter element.
Construction
The oil filter is installed on the right side surface of the cylinder block.
A spin-on type (full-flow type) oil filter has been adopted.
The bypa ...
Intake Air Temperature (Iat) Sensor
IAT Sensor No.1
Purpose/Function
Detects the IAT before it passes through the throttle body as basic information
for mainly determining the fuel injection amount.
Detects the IAT before it passes through the throttle body and inputs it
to the PCM as an IAT signal.
