The P0245 is tc turbo charger control

The P0342 : Camshaft position sensor, Signal to low intermittent fault

The P0445: Evap emission system valve, signal to low, permanent fault

The p0448 : Leak detection unit valve: signal to low

The P2088 : Intake Cam shaft reset valve : signal to low or not present

The p2090 : Exhaust Cam reset valve: Signal to low or not present

The p2401 : Leak diagnostic pump : signal low

The P0245, P0342,P2088 p2090 are engine related ?

how is the car driving ?

the P245,342 and 2090,2088 should make it have lack of power and hesitation or a misfire ?

please let me know

Thank You ***** ( aka -Customer)

It does have a misfire but no misfire codes and it won't go faster than 30mph .The cam sensor is brand new
Expert:  Chad Farhat replied 5 months ago.

you mentioned misfire , you had misfire and you changed plugs and coils ?

Expert:  Chad Farhat replied 5 months ago.

this low signal on everything make me think about a bad ECM , CAN't have all that not functioning at same time,

Customer: replied 5 months ago.
That's what I was suspecting since I have replaced the wiring harness too. I guess I will replace the ecm then
Customer: replied 5 months ago.
I changed all the plugs first and only 2 coils cause only 4 and 5 were misfiring. Then a few days later I got a misfire for all the cylinders except 6. So I replace the other 4 coils
Expert:  Chad Farhat replied 5 months ago.

all coils need replaced so replace that last one.

the p245 turbo control will cause the 2088 and 2090 if we dont have and ecm issue ,so check that valve

so all coil , all plugs new and then check all the vacum lines for cracks or leaking and replace as necessary especially one going to the control valve for turbo and clear codes and see what u get

the cam sensor , check the connector are you getting power & ground ?

if the turbo not opening correctly the air fuel mixture ratio will be wrong and you will misfire , the p0245 is a code earlier than the p0300 po301,po302 that u said u clear but it probably needed it the problem of misfire still would be from turbo issue

let me know

I think you have an ecm problem

Expert:  Chad Farhat replied 5 months ago.
