The supercharged V8 of the Range Rover. Powerful and costly to maintain - a misfire on a unit this large can wreck the catalyst fast.
Click a code for the full breakdown: symptoms, causes, and whether you can keep driving.
Random/Multiple Cylinder Misfire Detected
The engine control unit detects misfires occurring randomly across multiple cylinders, meaning combustion is failing intermittently in more than one cylinder.
System Too Lean (Bank 1)
The engine is getting too much air or too little fuel on bank 1 - the ECU has hit the limit of its ability to compensate.
Catalyst Efficiency Below Threshold (Bank 2)
Same fault as P0420 but on the second cylinder bank of V6/V8 engines - the catalytic converter on bank 2 is underperforming.
Catalyst System Efficiency Below Threshold (Bank 1)
The downstream oxygen sensor shows the catalytic converter on bank 1 is no longer cleaning exhaust gases efficiently.
Fuel Pressure Regulator Performance
The fuel pressure regulator is not maintaining pressure within the expected range, even though its control circuit tests electrically fine.
Camshaft Position Sensor Circuit Range/Performance
The camshaft position sensor signal is present but implausible or erratic.
