Time for izzy to buy an angle grinder, lol.
 
I started out with a pneumatic angle cutting wheel. It was okay but I couldn't get low enough. So shifted to hacksaw to the get the blade lower. Was a lot of work until I remember the blade was pretty old. Changed to a new hard carbon Craftman (the old blue ones) blade and it cut like butter, pretty impressive. Had the angle grinder ready to go, another ancient (30 year old) solid Craftman deal I have, but looking at it I decided to just remove the sharp edges, paint it and call it good. It goes better with my beat up truck, missing half the fender flares, rattle canned hood, and bashed in tailgate. All part of the antitheft device.
 
Got a better answer! After being forced to watch commercials on Hulu watching “the future of America”, I will not call it a stinger, it is an “early warning pedestrian crash detection system”. So I removed my pedestrian detection, EWPCDS as Lexus would call it .
 
Sooooo P0402, which I have been having since I got the truck 4-5 years ago. Finally got to use one of those landscaping flags, the long but thin metal stem, and used that to clean the intake hole below. The flag pole would go about 2 inches and stop, I could feel the blockage. And I pushed up and down until I finally broke through and the flag pole went down another few inches. Excellent, no more P0402.

But now I have a P0401 that wasnt there before.....what the hell....

You obviously did P0001 worth of damage. The good news is you might be able to ignore it for a while...when is your inspection due?
So I fixed one item, and now have another 401 to go? Sheeeeeeeet! Inspection is due 12/20, I have 13 months, better start...and gas mileage went from 13-14 to 10. Maybe I need to block the same hole again and continue living with the p0402, reseting it weekly
 
Checked all the FSM related stuff with vac pump and electric meter. Thermistor is good, EGR vac test passed, modulator test passed, filters cleaned and no carbon. Modulator hoses, one did hold a little vac, so cleaned both hoses with carb cleaner and compressed air, carbon cleaner into throttle body little hose connector too for good measure.
I didn’t remove the EGR and cleaned it as the fasteners look rusty and I don’t have a gasket. But the vac test on it does make the engine stumble at idle. Drove for a little, reset the codes, got gas. Now time will tell after more driving cycles

The one thing that I am not sure is the modulator to TB hoses. Modulator has Q, P, R , Q goes to EGR. P and R go to TB. But TB has E, R and P. The R-R marches, the P from modulator is connected to the E on TB. The TBpoints to the front of the engine and connects to another steel tube. What the hell? See the pics below. FSM doesn’t show this, but says connect R-R, P-P, Q-Q.

Welllllll. Sheet. Removed the TB, cleaned it and anything else I could get to. Put it back together and started engine. Now I see a coolant drip! I can guess the coolant hose from the TB down got dislodged somehow. Now to take it all apart again and trace that hose....

Hose clamp was loose on the bottom, fixed it, back to good enough. Will have to drove a few cycles to see if p0401 is taken care of. Used a lot of TB cleaner, so all I got is hope! And science...
 
if that hope and science doesnt work, remove the plug for the egr sensor , and install a properly sized resistor to make it appear the sensor is functioning properly. @Rice can tell you what the resistor specs are.
 
Which sensor? For the thermocouple? I did ordered the 4.7k ohm resistor cap. That’s my plan b, install that. I did test the thermocouple and it was working right though, per FSM.

Or sell that fancy pants OBD2 truck and find yourself a far superior and much faster ‘94 and pass inspection with all the lights lit up like a Christmas tree. As an extra bonus you get the much more attractive swoopy dash and plush, fabric headliner. Who needs 2nd gear start anyway?
 
2nd gear start has saved my bacon many times on hill climbs. But I was actually going in the wrong direction, looking at a 2003 and a 2009 ....
