SOURCE: P0174 code

I've had this problem for months, on my 1998 windstar 3.8 liter...I would clear the error with a OBD2 port device...

Check engine light may not happen again, until I drove 5 miles, then again 50 miles before problem came back...Always same error P0174.. Van ran ok..

I just looked under the hood, and there is a Rubber Elbow, right on top of the intake manafold, it joins to a plastic tube that goes to other hoses towards the firewall. The rubber elbow was mushy, not hard..Kind of decaying, due to oil residue?..I took off the badly cracked elbow (causing vacuum leak for sure) and replaced with a foot long 5/16th fuel line. I just looped the 1-foot fuel line hose in a circle, secured with couple wire ties and presto, elbow fixed with a piece of fuel line..I hope this solves my P0174 error, will find out this week. But I'm sure, the cracked rubber elbow must have had an effect on the vacuum system.

Several months ago, I went to ford dealer, when I noticed the elbow showing surface cracking, they said I'd have to buy an entire vacuum hose gizmo assembly, and All I need is the elbow. So I didn't replace the elbow.

SOURCE: Ford windstar check engine light comes on after

P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks. P0174 OBD-II Trouble Code


Technical Description

System Too Lean (Bank 2)


What does that mean?

Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exhaust.

Note: This DTC is very similar to P0171, and in fact your vehicle may show both codes at the same time.

Thanks.

SOURCE: I have a 2004 freestar

I just had the same thing. Engine light came on. Rough idle. Codes P0171, P0174, P2195, P2197. Within a week the idle got so bad it would die at stop lights. Seemed like a vacuum leak affecting the idle. Found it today. The elbow where the PCV tube enters the vacuum port on the upper intake was degraded, collapsed and had a whole in it. Wondered why it degraded. I disconnected the tube from the PCV valve and found it quite oily. I think the oil sat in the elbow at the intake because it is flat on top of the engine and could pool there, causing the rubber to degrad. Found a preformed piece of coolant hose at O'Reilly that was the right diameter and cut it to length. Put it on, runs like a charm. I ordered a new PCV valve because I think too much oil was coming through it and caused the hose failure._409.jpg_410.jpg

Code P0174 05 Corolla


I don't show any po174 for an 05 corolla. But I do show a po741, if thats the code you're getting.
It means theres a problem with the torque converter
clutch system. It could be the tcc solenoid. Either way, it's related to what you just had done.
Good luck.

2004 endeavor stalls and won't start. If I wait a while I can start and drive it again. Doesn't seem to have any pattern on when it will stall again.


How many miles? What grade fuel are you using? Have you ensured your air filter is clean? Do you get a check engine light? If so, have you taken it to autozone to pull the codes for free?
