I just had my V-AFC tuned and I'm getting a code 22 when ever I hold the car in vtec or on the high cam and allow the rpms to drop back down to the low cam without shifting. For example I'm in 3rd vtec is set for 4700 lo to hi switch over and 4600 hi to lo switch over I take the car to 5000 rpm and let off the gas, rpms start to fall, once the rpms are below 4600 the cel light comes on again. code 22 is for bad vtec oil pressure switch but the car does not do this when the vtec setting is left at the stock xover point. Any help greatly appreciated.
Peace.
