Question about Toyota Pickup

3 Answers

Hi, Im James. you were helping me with my toyota, but the system wont let me reply. incase you have many, I was the 94 4x4 with egr system codes. I replaced the egr valve and the problem persisted. I saw your directions for further testing, but I need to buy a vacuum gage, also I saw specific temperatures for coolant and gas or intake air. What is the best method for obtaining these temps? I experimented and removed the vacuum from the valve and plugged the tube I didnt notice a difference in the performance. also it seems like it may be running well before it gets up to operating temp and sucks thereafter. the gage in the dash has no #s but the needle stays in the middle so it doesnt look hot.

If egr is new, check the power to the egr with a meter. You should get 12 volts to the egr.
They also do sell temp testing gauge kits at the part store.

Hi, I remember you... If you don't want to replace the EGR itself, then what you do is eliminate it from the system. To do this: Remove the EGR Vavle asm. Then, make a solid gasket that you will insert between the EGR asm. and EGR mount. You are going to block off both the exhaust hole and the intake hole completly. You will have it all bolted together when done, but it will be eliminated as it will no longer allow exhaust gas to recirculate into the intake because of the blocking gasket you installed. And you will hook it up electrically as you did before you inserted the blocking gasket.

O6 Ave stalling


Hi James, Im AL the owner of Big As Auto Repair

James, there is a lot of things that can cause stalling, anything from. EGR Valve sticking in the open position. Vacuum Leaks large enough to cause stalling problems. WIRING issue where wires are frayed and grounding on the engine are brackets somewhere. FUEL PUMP that after heats up shuts down. Throttle Position Sensor that's BAD. and much more.

James each and everyone of this things and more will need to be diagnosed to find the one thing that's causing you problem. The engine size, make, model would help a little but stalling issues are hard to find. ONE THING THOUGH:

James, I want you to try one thing tap the Idle Air Control Motor and see if the idle changes. Next, tap on the TPS and see if the idle changes. Next, tap on the EGR Valve and see if the idle changes. Next, wiggle all the engine wiring and see if the idle changes. I hope one of these will lead you to the problem.

- faulty EGR valve
- EGR valve stuck closed
- problems with the DPFE sensor (Ford)
- problems with hoses to the DPFE sensor (Ford)
- problem with the EGR vacuum switching valve (Toyota)
- clogged catalytic converter
- carboned up EGR temperature sensor
- vacuum supply issues at the vacuum-operated EGR valve
- electrical problems with the EGR valve control circuit

My 02 grand am gt is acting up engine light is on went to autoparts store to get it checked out it threw codes p1404, p0404 and p0300 i already changed the egr valve twice and it wont help can someone plz...


code p0404 refers to Exhaust gas recirculation system (EGR)--range performance problem--- causes---hose leakage--wiring---EGR valve/solenoid
code p0300 refers to random/multiple cylinder/s ---misfire detected.---causes---spark plugs---ht leads---injectors--ignition coils---low compression ---wiring. Remember it is best to use genuine sensors/solenoids as the cpu is set to them. Try changing the egr solenoid

Oseneck99 toyota camery got a po401 code i replaced egr valve and egr pressure sensor. now i have codes po441 po446 please help.


Recheck all the vacuum lines near the EGR solenoid. The new codes are for the EVAP emissions system. they are codes for incorrect purge flow. You may have left a vacuum line of, switched a couple of lines or forgot to plug something back in.

I got trouble codes on and im not sure what to replace the one code is p0401 and p1195 and the car is a chrysler town and conutry 3.8 please help


Hi:
Both codes are EGR system codes. The egr valve can be removed and cleaned to start with, and the EGR pressure sensor is another possibility that could cause the codes.
