P1382 indicates no signal from cylinder position sensor. This would cause operation in "limp home" mode and may cause the P1259 (vtec malfunction) code.

First check that something is not broken or disconnected at the distributor (cylinder position sensor in distributor). If everything checks OK, a new distributor housing is required to replace the sensor.

Fix cylinder position sensor, and then see if P1259 remains after resetting ECU (disconnect battery negative cable for 20 secs).

good luck

 

The P1259 - VTEC System Malfunction should also be addressed, as it may be due to low oil pressure. The VTEC system relies on oil pressure; so, check that the oil level is okay. The code can also be caused by the VTEC solenoid valve, VTEC oil pressure switch, wiring, connector, or ECM/PCM.
