Refer to Testing for Continuity and Testing for Intermittent Conditions and Poor Connections. Here is the code description for code p1404 I forgot to post it on my first post sorry about that. Basically you have any problem with the air system. Any tips would be very appreciated. Did you find and correct the condition? I've already received a high dollar ticket for expired inspection, but this is my work truck, so can't avoid driving it. I put it back together, cleared the code and drove it for about thirty minutes.
After reading many items it says this could be multiple issues including an o2 sensor. I posted the code description for code P1404 so you have a better understanding on what is going on. Same as the valve sticking in the open position, a closed valve can sometimes be cleaned to fix the problem, but replacement is also occasionally required. Vacuum pressure may also be affected by other associated components within the vacuum system. I do not know what to do at this point. I am going to remove the valve , clean and replace gasgets first before doing the 100 bucks deal.
I took the car to a dealership to get it checked out and a code p0104 has pop up on there scanners. Refer to Wiring Repairs in Wiring Systems for diagnosis and repair. The condition is present for more than 20 seconds. What repairs can fix the P0404 code? Later and sorry I didn't post my findings on the 1st post sooner. It can be as simple as a loose connector that just needs to be secured properly.
The kid at the mechanic shop said it was the egr valve and to replace it was a bit over 300. Exhaust gases can escape and accumulate within the engine compartment and create a safety concern. If it doesn't then repair the ground circuit. The exhaust gases are routed back to the intake for combustion again. Did you find and correct the condition? If a problem is found, repair as necessary.
Refer to Testing for Intermittent Conditions and Poor Connections, and to Connector Repairs in Wiring Systems for diagnosis and repair. Since the valve was replaced and is operating correctly it would need the calibration update at the dealer. . Yes it would be the same issue. It just recently failed inspection for the code p0404 as well. I have checked the wiring and everything seems ok, I will clean the contach on the connector when I have it all apart.

Intermittent problems are hard to solve, since if they're not present and causing the problem when you test them. Refer to Wiring Repairs in Wiring Systems for diagnosis and repair. I also took the initiative took get the car scanned at multiple dealerships before actually get the maintenance done to the car and the same code appeared.
It may be as simple as a defective vacuum line, a broken slice or a broken tee. Thanks Are you in California. If any of these conditions still exist, cat failure is once again intimate. I will check of proper vac presure and follow up. My Muffler man sawed it in to and showed me the inside. Many thanks for your help. The gaskets prevent contaminate intrusion.
