Help...3 engine codes at once...12,33, & 34 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

12 Mass Air Flow Sensor
33 Heated Oxygen Sensor
34 Knock Sensor

I checked the on board diagnostics and my engine light blinked these codes. I talked to a mechanic who said he ran into this exact problem before and changed the MAF, O2, and Knock sensor AND still the problem persisted.

Does anyone have any idea what this could be or ran into this problem? It would be disturbing if I replaced all 3 and still have the engine light on.

Oh yah...it's a stock 95 KA
