Common Car Sensor Problems in Kenya and How to Fix Them
Modern vehicles rely on sensors to monitor performance, safety, and emissions. When these sensors fail, your car’s efficiency and safety are compromised. Understanding the most common car sensor problems in Kenya helps you identify issues early and fix them before they cause bigger damage.
Common Car Sensor Problems
1. Oxygen (O2) Sensor Failure
The oxygen sensor measures exhaust gases to adjust the air-fuel mixture. When faulty, it causes poor fuel economy, black smoke, and higher emissions.
Fix: Replace the sensor every 60,000–100,000 km or as recommended. Book Engine Diagnostics for accurate checks.
2. Mass Airflow (MAF) Sensor Issues
The MAF sensor monitors air entering the engine. A bad MAF sensor leads to rough idling, stalling, or engine hesitation.
Fix: Cleaning may help, but replacement is often necessary.
3. Coolant Temperature Sensor Problems
This sensor monitors engine temperature. If it fails, your car may overheat or consume excess fuel.
Fix: Replace faulty sensors and check cooling system health.
4. Throttle Position Sensor (TPS) Faults
The TPS ensures smooth acceleration. A faulty sensor causes jerky acceleration or poor throttle response.
Fix: Replace the sensor and recalibrate if needed.
5. ABS Sensor Malfunctions
ABS sensors monitor wheel speed to prevent skidding. If faulty, the ABS warning light turns on, and braking becomes less safe.
Fix: Clean or replace damaged sensors to restore safety.
6. Crankshaft or Camshaft Position Sensor Failure
These sensors control ignition timing. Failure can cause engine misfires, stalling, or failure to start.
Fix: Replace sensors immediately to prevent engine damage.
Why Car Sensor Problems Are Common in Kenya
- Dust and dirt from roads clog sensors
- Poor-quality fuel damages sensitive components
- Irregular servicing delays detection

FAQs on Car Sensor Problems in Kenya
Can I drive with a faulty sensor?
It depends. Some cause reduced performance, but others, like ABS or crankshaft sensors, are dangerous to ignore.
Do sensor problems always trigger the check engine light?
Most do, but not all. Regular diagnostics help catch hidden issues.
Can dust really damage car sensors?
Yes. Dust and debris are a major cause of sensor failure in Kenya.
Are sensor repairs expensive?
Some are costly, but early detection reduces expenses.
Can I clean sensors myself?
Some, like MAF sensors, can be cleaned, but most require professional tools.
