last week i have installed a new (used) engine for my car listed above ivtec dohc.after driving for 10 minutes, I had a problem, it cuts off and in scanner i read this : and the engine burned 2 quartz of oil in 5 days! i replaced the VTEC Oil Pressure Switch, but i had not a good result. so I replaced again the engine. and I had the same problem, and i replaced the VTEC Oil Pressure Switch, but i had not a good result, in addition I have now two new codes: so, do you think that the mechanics made something wrong in wires ? or what could it be ? thank you

When the engine shuts off, can you hear the fuel pump run when you turn the key back to on?

When you crank it, does the tach move up a little to show engine RPM? The crank sensor sends a signal to the ECM for this. If it is the issue, it would be one of the codes.

1. Disconnect the CKP sensor connector (A).
2. Remove the CKP sensor (B).
3. Install the sensor in the reverse order of removal with a new O-ring (C).
