2006年7月30日 · I OBD scanned my car 2 weeks ago. it pulled up that i have an code P0400: EGR Flow Malfunction. i went to a mechanic to get an opinion. he told me it was the EGR valve that was causing the problem. alright, so i looked around for an EGR valve and found one. i relplaced it along with all of the vaccum hoses in the EGR system. i disconnected the negative …

2009年10月25日 · I've been getting both the P0400 & the P0325 code at the same time, my dad swapped out the EGR valve today, and i reset the code. I drove it around, then shut off the car let it sit for about 2 hours and started it up again, and the CEL light came back. I scanned the car, and the same 2 codes came back. So should I replace the Knock sensor now?

2010年2月24日 · The EGR flow code is available on all Altima ECUs. A CONSULT scanner, or OBDII scanner, will report it as a P0400 code while the ECU self-diagnostic will flash a code 32 on the Check Engine light. I could go at length to explain how this system works but I think it probably would be better to point out the most common problems in this system.

2008年11月17日 · I recently did an intake manifold gasket repair for a P0304 (cylinder 4 misfire). I put it all back together and now I am getting a P0400 (insufficient egr flow) and a P0325 (Knock Sensor). I tried cleaning the egr because I read in a forum that a knock sensor code usually comes with another...

2008年2月2日 · I have a 2000 Altima that recently threw a P0400 code (EGR Flow Malfunction). I've had some trouble figuring out what the problem is. I looked around and found that the P0400 code often means clogged hoses, so I cleaned out the …

2009年6月10日 · I have 3 CEL Codes(P0400 P0325 P1105). Engine runs good but the vaccum line have to be messed up and maybe the knock sensor was bad from the previous car. I have Mitchell on Demand but the Vaccum diagram is very confusing. Car is needing to pass emissions in July so I Really need to get it fixed. Any help??? Thanks

2011年8月6日 · Got 2 codes: P0400 and P0325(knock sensor). After searching the forum, I went and pulled out the EGR sensor that's closest to the firewall and found that it was caked in black carbon. After cleaning it off without using any kind of chemical, I plugged it back in, reset the ECU, and drove about 4 miles before it came right back on again.

2010年3月29日 · I'm currently in the process of diagnosing the reason behind the P0400 code my ECM keeps throwing. I've checked the obvious vacuum hoses, all seem to be in fair condition and hold vacuum. The EGR valve itself holds vacuum, and when pressed upwards while the engine is idling the engine will...

2016年6月16日 · "On many 90's and early 00's Nissan vehicles (e.g. Pathfinder, Altima, Maxima, Frontier, Quest) the code P0400 could be caused by a carbon buildup blocking the air flow around EGR temperature sensor. The repair involves removing and cleaning the EGR temperature sensor an the EGR tubes, ports and passages.
