my p1 is running like **** low down .... ive just plugged in my laptop and got code of knock sensor, P0336 - Crankshaft position sensor circuit range/performance problem
P0111 - Intake air temperature Sensor Range/Performance problem
P0037 - HO2S Heater control Circuit Low (bank1 Sensor 2)
and this one just popped up as im typing P0604 - internal control module random access memory error

Can any 1 shed some light on my engine problems

 

Can you clear the codes take it for a drive then re read codes and see what comes up.

 

i went to do that via jollygreenmonster by connecting the green and black wires under dash but it says to reset ECU that there must be no fault codes then take it for a drive but when we done this it was flashing Knock sensor.

 

Well the knock sensor is the first thing to check. Sometimes all you need to do to it is take it off clean the block and sensor and connection and refit it using a torque wrench.

 

Some of those codes are not relevant to a P1, what are you using to read them? You could be getting incorrect information.

If it's flashing knock sensor code. then that's where to start. Flash codes are accurate.
