Why a Fault Code Isn’t the Full Answer | Mobile Mechanic Explains

Today, a customer sent me a photo of their scan tool and asked, “How much will it cost to fix this?”

It’s a common question.
But fault codes aren’t the full answer — they just tell us where to start looking.

My job is to take that code and dig deeper:
→ Inspect the wiring
→ Test the sensors
→ Check for split pipes
→ And rule out all the possible causes.

Because every fault code can have a dozen different root causes.
That’s why when I recommend an inspection — even if you’ve already had the codes read — I’m not trying to sell you more diagnostics.

I’m trying to sell you the most valuable thing of all:
The real answer to your fault.

That’s how you fix cars properly. Not by guessing. By knowing.
