I have that same code. To make sure I'm looking at the right vacuum hose, could someone please post a picture of it?

I got a plastic 90 degree part and used straight hose on it. Works perfect.

This code popped up on my dash the other day. My jeep was stalling randomly so I replaced that 90 degree elbow connector st the intake manifold and cleared the code. The light has stayed off but the jeep still stalls. everytime it stalls, I have to disconnect that connector, start the engine, then reconnect it. What effect does this vacuum line have on the engine and why is it still stalling because of it! I replaced the fuel filter thinking that was the problem at first. This is on my 2001 Jeep grand cherokee 4.0

p1494

My 2001 cherokee had the same problem. Check engine light came on; code p1494. When I googled it, this forum was the first thing that came up. After finding out what the code meant, & the likely cause, the 1st things I checked were the vacuum line connections to the intake manifold. Sure enough, the front most vacuum line was off. The 90 degree elbow that connects the line to the manifold was dried out & stretched out. It cost $3.00 & took 10 minutes to replace. It's been fine since. Thank you very much!

2001 XJ DTS Code P1497

Went to start my 2001 XJ Limited and it coughed, ran ruff, and the engine light cam on. I restarted and it ran fine. Code P1497 came up, I cleared it and the light stayed off for 2 days then came back. I found the Evap pump and traced the vacuum line back to the intake manifold, and found that the line had disconnected. However, the rubber elbow that connects the line to the intake manifold was getting old so I replaced all the rubber connectors on both ends. Solved my problem and it was a cheap repair.

Please help ASAP. I have a 2001 jeep wrangler I need to get smoged. Did not pass showing code P1494. After fail I noticed 90 vac live off, which I replaced. I also recently replaced battery prior to having it smoged. After fail, I had the smog guy clear codes hoping I could drive it for bit in hopes of computer re-learning or resetting itself. After 1 day appx 100 mi, scanner does not show P1494 but still has two blinking codes C & EV. I understand It will only pass smog with 1 blinking code. Can anyone tell me the fastest way to have jeep reset itself after battery replaced & codes cleared? Is it days, miles,??? Jeep dealer is too busy to see it, so im dealing with joe blow smog shop & he just keeps having me drive in circles..& need done asap

same deal here, but haven't popped the hood to take a peek yet. Unfortunately the pics that were posted are broken now. Can someone repost a pic of the elbow?

Hey guys, I just got a 2000 jeep cherokee a few weeks back, and I've got this same coding problem. I inspected the hoses and I can't find anything amiss. If any of you would be willing to take a quick pic of that 90 degree elbow you're talking about that would be great. I'm not sure if I'm looking at the same thing or not.

So I'm having a very similar issue to this guy. Got the check engine light, got the P1494 code, found the elbow off at the intake manifold and put it back on, two days later it stalls going down the highway. Let it sit for about an hour and it will start again and get me about five miles down the road before stalling out again. I put a fuel pressure gauge on it and when it stalls out the fuel pressure is at about 30psi and dropping fast. I'm currently in the process of replacing the fuel pump and not having a fun time. I'll let ya know how I make out.

Thanks again Jeep Forum
