8 Common Fault Codes We Diagnose

Your dashboard warning light stores a code. Here is what the most common ones actually mean in everyday language.

P0300
Random Misfire Detected

One or more cylinders are not firing correctly. Common causes include faulty spark plugs, coil packs, or fuel injectors.

P0420
Catalyst Efficiency Below Threshold

Your catalytic converter is not cleaning exhaust gases efficiently. Often caused by engine misfires or oil/coolant burning.

P0171
System Too Lean (Bank 1)

Too much air or too little fuel in the combustion mixture. Common causes: vacuum leak, dirty MAF sensor, or weak fuel pump.

P0113
Intake Air Temp Sensor High

The IAT sensor is reading an unusually high voltage. Usually a faulty sensor or damaged wiring harness near the air intake.

C0035
ABS Wheel Speed Sensor (Front Left)

The front-left wheel speed sensor is sending no or incorrect data. Can cause ABS / traction control failure on Uganda's wet roads.

B1000
Airbag / SRS Module Fault

The supplemental restraint system has detected a fault. This must be resolved — airbags may not deploy in a collision.

U0100
Lost Communication with ECM/PCM

The body control module cannot talk to the engine control module. Often a CAN bus wiring fault, blown fuse, or failed ECU.

P0601
ECU Internal Memory Checksum Error

The ECU's internal memory has been corrupted or has failed. Requires ECU reprogramming or replacement with coding.

Frequently Asked Questions

Still unsure? Here are answers to the questions we hear most from our customers.

How long does a full diagnostic scan take?

A comprehensive OBD2 scan of all vehicle modules typically takes 30–45 minutes. We then spend another 15–20 minutes reviewing the results with you in plain language, explaining what each fault means and recommending the most cost-effective repair path. You leave with a printed report you can keep for your records.

Can you diagnose vehicles without an OBD2 port (older cars)?

Yes. For pre-OBD2 vehicles (generally pre-1996), our technicians use oscilloscope-based diagnostics, manufacturer-specific breakout boxes, and wiring diagrams to manually trace faults. While the process takes longer, we can still identify the vast majority of electrical and mechanical issues without a standard OBD port.

My check engine light came on but my car drives fine — should I still come in?

Absolutely. A steady check engine light often indicates a non-urgent emission or sensor fault — but it can also be an early warning of a developing problem that will become expensive if ignored. A flashing or blinking check engine light, however, signals an active misfire that can damage your catalytic converter within minutes. Come in immediately if the light is flashing.

Do you support Toyota, Nissan, and other Japanese brands common in Uganda?

Yes — Toyota, Nissan, Isuzu, Honda, Subaru, Mitsubishi, and Mazda make up the majority of vehicles we service. Our Autel MaxiSYS scanner covers all these brands with full system access and active test capability. We also have dedicated interfaces for Toyota Techstream and Nissan Consult III Plus for deep-level diagnostics and programming on Japanese vehicles.
