Mazda CX-5 KE 2011–2017 Common Wiring and Sensor Problems
1. Sensor problems
ABS sensors:
Often fails due to dirty or damaged wiring.
The error on the instrument panel is accompanied by disabling the ABS and stabilization system (ESP).
Reason: sensor damage or corrosion of connections.
Tire pressure sensors (TPMS):
False warnings about flat tires.
Rapid discharge of batteries inside the sensors.
Oxygen sensor (lambda probe):
Problems with incorrect composition of the fuel-air mixture.
"Check Engine" error and deterioration of fuel consumption.
Parking sensors:
False triggering or failure.
Often associated with dirty or damaged wiring.
Rear view camera:
The image may disappear due to breaks or problems in the connectors.
2. Wiring problems
Frayed or broken wires in the doors:
Over time, the insulation of the wires can wear out, causing problems with the central lock, windows or speakers.
Corrosion of connections:
More common in regions with high humidity or when using aggressive reagents in winter.
Problems with the headlights, turn signals or rear light electrics.
Blown fuses:
Occurs when the circuit is overloaded, for example, when using powerful additional accessories.
3. Lighting system problems
Headlights or rear lights are faulty:
Often caused by poor contact or corrosion in the connectors.
Sometimes there is a malfunction of the lighting control units.
4. Control unit (ECU) problems
Sometimes there are communication errors between the ECU and other modules (e.g. ABS, multimedia).
Reflashing the software usually solves the problem.
5. Generator and Battery Problems
Weak Battery:
Can cause electronic malfunctions (e.g. slow operation of windows).
Alternator Failure:
Leads to battery discharge and unstable operation of electrical systems.
Recommendations
Regularly check wiring: especially in vulnerable areas such as doors and trunk.
Clean contacts and connectors: to avoid corrosion.
Use genuine components: for repair and replacement of sensors.
Error Diagnosis: Check error codes in a timely manner via OBD-II scanner to avoid further problems.
