Engine Mechanical problem
1996 Toyota Pickup 4 cyl Two Wheel Drive Manual 116000 miles
I have the P0402 code. I understand it's an EGR system problem. I tested the EGR valve, using vacuum to the valve and the engine dies. It works OK. I tested the VSV switch and it's operating. I assumed it would then be the vacuum modulator so I replaced it. The ligh came back on in about 25 miles.
Do you have any idea what the problem might be?
