2002 EGR Vacuum Solenoid

Hi, can anyone help me with the location of an EGR vacuum solenoid? 2002 Toyota 4Runner.. Thank you,

 

No such thing.

No EGR on the 3400.

What are you trying to do?

 

I have the check engine light and two other lights on. The truck feels like it has no real power till it warms up.

 

Codes?

Any auto parts store will run their code reader on your car for you for free...because they want to sell you parts. Just get the codes and report back.

 

That's what I did. I went to Auto Zone and ran the report. It came up with 3 codes. P0446 EVAP vent control Solenoid circuit malfunction. P0440 Evaporative Emissions Systems and P0441 Evaporative Emission System Incorrect Purge Flow.

 

Evap codes are not really an issue in regards to any loss of power. The Evap system works by recirculating gasses via the fuel tank and charcoal canister and fuel neck filler, etc. Nothing that really affects how the engine runs.

I was expecting to see a misfire code or something. If the car idles fine, revs fine...are you sure it's not a tired transmission? I know my 2002 always feels slow to shift when cold. Plus, for the last 100k miles after I start her, I shift into drive for a second and then reverse to back out of my driveway.

To fix the Evap codes, you're probably going to have to drop the tank and replace the valves and gaskets on top of the tank. These are notorious for drying out after 20 years. Once they dry out or crack, they allow gas vapors into the air which the computer detects and throws a code. Toyota also throws the VSC\TRAC lights too but those have nothing to do with the issue. While the tank is down...replace the fuel pump (Denso Only) and replace the sending unit. They don't last forever and since they have to be pulled to replace a gasket, whoever does the work, should charge you minimal work time.

My thread for my P0440 fix: I know it was a bit overkill, but for me, I do all my own work so I figured I could justify replacing nearly the whole system.

To find the actual leak, you'd need to do a smoke test. It's almost certain to be on the top of the tank.

For the other 2 codes, they may clear up after fixing any leaks and the P0440 code. Otherwise the charcoal canister (above the spare tire) or the actuator valve in the engine bay (behind the fuse box on the driver's side) may be the issue. Those can be replaced without dropping the tank again.

 

Thank you so much for taking the time to explain that all to me. I really appreciate it.
