02 F150, 5.4 gas motor, about 338k miles. Bought this truck well used so I would have a truck when I needed one. Someone has removed the heater control valve. I've got a new one, but there is a port on the top for a vacuum line, but where this line plugs into.
View 1 RepliesI noticed a vacuum line hanging under my 98 F 150 4x4 I traced it out to my front axle question is where does the other end go I have looked but no luck to where it goes.

View 2 RepliesRecently I have been having a strong gas smell coming from my 1997 F150 Supercab 4.6L 2wd. It is not happening all of the time. I have also been hearing what sounds like a vacuum line leak. A loud shrill which varies with the engine rpm. This also does not happen all of the time.
View 1 RepliesGot F-150 4.6 cooling system leak on the heater line (farthest back line) coming out of the block. Fitting looks to be steel. How does it attach/ do I need to remove the Intake to replace?
View 5 RepliesI have an '04 Explorer Limited and lately only blows cold air. I've read about the blend door motors but it's been too cold in MI to want to do much--so the truck sits.
When I was troubleshooting the problem I found that I'm not getting any vacuum signal to the heater valve in the coolant line. Before I contemplate removing the console & doing surgery on my dash I'd like to know for sure what position the valve should be in when heat is called for.
All the other vacuum actuators seem to be working normally and there's no disconnected hoses under the dash; and no leaks. Coolant reservoir is full.
Question, I have a 2003 VW Golf GLS 2.0L AHV (5 speed). The brake vacuum line is cracked after the check valve on the intake side. I looked up the part number on the hose (at work and don't have it on me at the moment), did some research and noticed some revisions to that part number. Eventually settled on [URL] ..... (I ordered a new one since I needed to order a few things). Needless to say, I am beginning to think I ordered wrong.
I noticed that the check valve on the new hose has a 3rd piece that a smaller hose looks to clamp on? The check valve that is in my car doesn't have that. Did I order the wrong part? or did I need to be a cap?
I have an emissions test coming up. I have 3 P codes that I'd like to eliminate before then. I don't want to "fix" the issues they are telling me about. Just make the codes go away. I know why they're there I just need to get rid of them.
What I have coming up is:
P0475 Exhaust Pressure Circuit Valve (result of EBPV delete)
P0541 Intake air heater A circuit low (result of aih delete)
P0640 Intake air heater control circuit (also result of aih delete)
What resistors I'll need and where to put them in?
When the idle control valve is replaced does the ECU have to relearn the settings?
View 2 RepliesI need the PCM pinout for a 2002 F150 4.6 For the Purge Control Valve Circuit. If possible the wire schematic would be nice also. Getting code PO443 (( hard code )) I have checked battery voltage at valve connector with key on (( 12.2 volts )) valve resistance is at be 35 ohms so I'm thinking I may have a bad wire or a bad PCM .

View 8 RepliesSwapping a 2004 2.4 motor and trans into my 03 that has a locked up motor. Pulled the motor out of the 2004 yesterday and started tearing into my 2003 today and noticed that the 2004 motor and harness doesn't have the provision for the vacuum control valve mounted in the air cleaner lid like the 2003 has. Since I'll be using the harness and ECM from the 2004 into the 2003, wondering if I can just either use the lid from the 2003 and keep the VCV(hook lines back up) but not have electrical connection going to it. It will basically be pulling the vapors 100% of the time since there is no power going to it and it's a naturally open valve.
Using the harness from the 2004 that I pulled with the engine, there is no way of hooking up to the VCV since the 2004 didn't have one(hence no electrical connector).
While diagnosing a problem with my rear AC not working, I pulled the rear plenum apart. I noticed the rear heater coil was really hot even though I did not turn the heat on at all that day.
I suspect a bad heater control valve. The one that stops hot coolant from going to the core when the AC is on. I have manual temp controls so I assumen it is vacuum controlled. All data does not give me a location or vacuum routing specs for the valve so I am asking here.
1) Where do I find the heater control valve?
2) Does it shut off the coolant to both the front and rear heater cores or just the front?
My wife has a stock 03 Passat 1.8t.
1. The car seems to shift too soon from 2nd to 3rd and i can hear the turbo drop pressure. It sounds like a quiet blow off 3 or 4 times when it shifts from 2nd to 3rd.
2. There is a vacuum control valve that sits on top of the air cleaner box and it ticks a lot. it has a electric plug going to it.
3. The car has a rough idle while in drive and sometimes shifts hard. I changed plugs, trans flush and filter change.
I would take the car to a VW dealer but the closest one is about a hour away and my wife needs the car.
Bought my Ranger brand new, and I try to maintain it well. Most of the 90,000 miles are highway. Anyway, the OEM coolant was supposed to be good for 100K miles, but since I hadn't done anything in 89K, i have a lengthy commute and the coolant was getting discolored, I figured that no harm would come in having a drain/refill. This was approx. The heat worked flawlessly. Fast forward two weeks, and my local shop performed an oil change (not the quick lube that did the coolant replacement). I was informed of three things:
1) my coolant was low,
2) my heater control valve was leaking (which I was shown), and
3) when hoisted I was shown that a slight residue of coolant -- not necessarily fresh -- was on my water pump.
I was told that 'down the road sometime a water pump could be in my future'. Again, the heat worked flawlessly, and I didn't want to be out-and-about in winter and run out of coolant. So, the shop replaced my heater control valve and topped off the coolant (approx. 1/2 - 1 gallon). Heat worked flawlessly. The last couple days, I noticed two things.
First, heat trickles out on low and medium setting, and second, it takes a long time to warm the vehicle. So, my limited research tells me two things. If coolant is present, and I have heat (of some sort), then, the water pump and heater core are probably fine. Diagnosis says to check the thermostat first, correct?
I just purchased an 97 E350 (15 Passenger) and I notice that the two rear heater lines (along the driver side) are rotted and is showing sign of minor leakage. Can I simply replace them with rubber heater hoses or do I need to get the factory heater lines?
View 6 RepliesWhere Gen5 Camry heater control tab/valve is located? I can't seem to find in engine bay. Is it in cabin under dash? Under drivers side dash, I can only see heater control valve cable. I have got a hot coolant coming to heater core, so heater control valve must have gone bad.
View 6 RepliesReplacing a heater control valve for a 2004 Jetta? My car's vents only blow hot, and I checked the cables and saw that the control arm was disconnected. I tried to put the cylinder piece back in and had some luck, but I can't get it to sit tightly in there and it keeps falling out. Also, it still wont change the temperature coming out of the vents. I assume that something broke on the inside piece that the cylinder connected to.

Here is an example of what mine kind of looks like, but mine is way more loose.
How to fix SES P0670?? I understand there's a whole procedure on checking fault.
P0670:GPCM Glow plug control module control line failure. Open/grounded circuit, open/shorted GPCM, failed PCM
But how did you resolve problem? replaced GPCM, found open circuit, short --if so where?-- or replaced with updated harness.

I have a 2003 Ex with the 7.3. There is a leak in the rear coolant line just in front of the rear right tire. Is there any way to bypass the rear heater under the hood?
