I'm getting these p errors: P0010, P0013, P0020, P0102, p0113, P0118, p0121, p0123, p0338, p0343, p0348, p0368, p0393, p0553, p0778, p1343, p2135, p2716 and C1201. Engine cranks but won't start. Is my ECU damaged? I checked the cables by multimeter from many of the sensors to the ecu connector d74 and there's no problem. I Checked the fuses, no ground short, new battery, half fuel tank. I cleaned the throttle and MAF, and replaced the spark plug then it worked, later I changed the battery, and cleaned contact d74 and it shut off.

The error codes you provided are related to various components and systems in your vehicle. While it's difficult to pinpoint the exact cause without further diagnostic information, it's unlikely that a damaged ECU (Engine Control Unit) is the sole reason for the engine cranking but not starting.

Here are some insights into a few of the error codes you mentioned:

P0010, P0013, P0020: These codes are related to the camshaft position actuator circuit. They indicate potential issues with the variable valve timing system.

P0102: This code indicates a problem with the Mass Air Flow (MAF) sensor circuit. It could be caused by a faulty sensor or an issue with the wiring.

P0113, P0118: These codes are related to the intake air temperature sensor and engine coolant temperature sensor, respectively. They suggest potential problems with these sensors or their circuits.

P0121, P0123: These codes pertain to the throttle position sensor, indicating issues with the sensor or its circuit.

P0338, P0343, P0348, P0368: These codes are associated with the crankshaft or camshaft position sensors. They may indicate problems with the sensors or the related circuits.

P0393: This code is specific to the camshaft position sensor circuit for camshaft 2 in bank 2.

P0553: This code indicates an issue with the power steering pressure sensor circuit.

P0778: This code is related to the 2-4 brake pressure control solenoid circuit. It could indicate a problem with the solenoid or its circuit.

P1343: This code is specific to the ignition coil group 4 and could indicate a problem with the coil or its circuit.

P2135: This code refers to a problem with the throttle/pedal position sensor/switch circuit.

P2716: This code indicates a problem with the pressure control solenoid "D" electrical circuit.

C1201: This code is related to the engine control system malfunction and could indicate a problem with the ECU or a communication issue between the ECU and other modules.
