Vsc and engine light on
Hello
I have a 08 es350 with vsc light and multiple engine codes.
At first i had a code pointing to my #6 ignition coil and i have fixed that and light went away. Now I'm getting the following codes.
P0352 (showing twice on code reader)
P2240
P2237
Any ideas what the culprit could be?

I agree first check your spark plugs but it could be something else.
A/F = Air - Fuel Ratio Sensor - Code P2240 is an indication that the ECM is getting a signal from the air-fuel ratio sensor that it may be shorted or open. The ECM cannot control the fuel properly until the signal is fixed. You may have poor fuel mileage and various poor drive symptoms.
Code P2237 is a code indicating the O2 sensor heater circuit is open or shorted causing the circuit voltage control to be open. This will cause the fuel feedback control to not work and the ECM to put the engine into failure mode.
P0352 is a generic OBD-II diagnostic trouble code (DTC) that your vehicle's powertrain control module (PCM) or engine control module (ECM) logs when there's an issue with the ignition coil circuit. The trouble code definition for P0352 is “Ignition Coil B Primary/Secondary Circuit Malfunction”.

Maybe bad coils or 02 sensors but that is a guess based on codes. Rather than throw more parts based on codes, it may actually be useful to have someone more skilled in diagnostics take a look.
