Hybrid MPG Drop Diagnosis London
Pinpointing the Hidden Faults Causing Lost Fuel Economy
📉 Is Your Hybrid Drinking Fuel? Get to the Root Cause!
Don't just drive less efficiently. Let our experts diagnose the issue precisely:
Our Specialized MPG Drop Diagnostic Process:
- 🟢 **HV Battery Health Check:** Full assessment of the High Voltage battery State of Health (SOH) and degradation, a primary cause of lost electric assist and MPG drop.
- 🟢 **EGR System Inspection:** Diagnosis of carbon build-up in the EGR valve and intake manifold, forcing the engine to run less efficiently (common in Prius Gen 3).
- 🟢 **Oxygen Sensor/Catalyst Check:** Scanning for slow or faulty O2 and Air/Fuel sensors, which cause inaccurate fuel mixture and significantly reduced MPG.
- 🟢 **Inverter Cooling Status:** Checking the inverter cooling pump and system integrity; overheating components reduce system efficiency.
- 🟢 **Engine Running Diagnostics:** Advanced live data analysis for engine faults like misfires, sticky piston rings, or inefficient combustion.
- 🟢 **Clear Action Plan:** Providing a prioritized plan (e.g., Battery Reconditioning, EGR Clean, Sensor Replacement) to restore your vehicle's peak fuel efficiency.
