I have codes p1259, p0141, p1457, p0325, p0303

Question

OK I have a 99 Honda accord and p1259 code came up. My oil goes out at least every 2-3 days sometimes everyday noticed my gas burns faster & my car jumps when it hits 40mph or higher when oil is low. Anybody got any clues to what the problem is? Or how to test it?

Answer 1

P1259 VTEC system malfunction

P0141 Secondary heated oxygen sensor heater circuit malfunction

P1457 Evaporative emission control system leakage (EVAP cansiter system)

P0325 Knock sensor circuit malfunction

P0303 Misfire number 3 cylinder

When you have a VTEC system malfucntion either event happens the VTEC starves the cylinder head for oil , or the VTEC just does not function. When the VTEC malfucntion the knock sensor pick up the engine knock. The best way to reolve the issue is to replace the VTEC solenoid, The misfire code would be a seperate issue, move the number 3 ignition coil to a different cylinder, and retest.If the misfire follows the where the igntion coil is at the fault would be with the igntion coil.
