Golf IV / Jetta IV :: Boost Gauge Is Reading Peak Of About 15 - 16 PSI

Okay, here's the car

AWP 1.8t mk4 GTI.

- stock DP

- Forge 007 splitter adjusted 25 clicks

- Swiss cheese stock intake with k&N high flow

- APR stage 1 93 tune.

My boost gauge is currently reading peak of about 15-16 psi. I replaces some vacuum hoses that appeared to be worn, and to no avail. I have no CEL, and no codes thrown at all. This sound like a boost leak.

Golf/GTI VI :: Gauge Not Reading Full Boost After VF Intake Install

I installed a VF intake a few weeks back and noticed my car is peaking at around 14-15 PSI max according to my boost gauge, when it used to hit 17 peak. I'm not sure if I may have a leak nor have I checked it via vag-com.

It does feel a bit off, but for as far as I know the gauge could be messed up now.

Just wondering if there would be any immediate signs (sounds etc...) of whether there would be a leak, or what other problems may cause this.

Prius (Gen 2) :: Gas Gauge Is Not Giving Accurate Reading

I've been letting my wife drive the 2007 Prius since I've been cycling in to work. I got in the car last night and thought "Wow, almost a full tank". I then realized that only 1 pip was missing for 208 miles! The MFD was reading average mpg around 43, so this was bizarre. Usually the first pip drops around 110-120 miles.

By the time we got back home, I was around 220+ and 2 pips were gone. This is usually when half the pips are gone. Is this something I should be concerned about? Should I reset the gauge?

Silverado :: 2004 - Gas Gauge Incorrect Reading But Still Calculating MPG?

My '04 gas gauge started moving around, slowly rising from empty with low fuel light on to the correct position, a few days later it would rise to less than the correct reading, and now it's just parked on empty with the low fuel light on constantly.

After reading all the similar complaints, I'm guessing it's the fuel sensor. I've been using the "personal" trip odometer to monitor my miles so I don't run out of fuel. I cycled through the odometer settings and it's showing a mpg reading (which clears when I resent the personal trip odometer) so I'm wondering if it may be the gauge instead of the sender. How it determines how much fuel is consumed in order to calculate the mpg? I would think that if the sensor is not working, it would not be able to calculate mpg. Or does it use another method?

Accord :: 93 EX Sedan - Temperature Gauge Reading Cold

I have a 93 accord ex sedan, 4 cylinder, automatic that I bought in August. I live in South Dakota & it's starting to get cold here. When I first bought the car the temp gauge was working fine in that it would move to the middle of hot/cold range. Recently, I've noticed the interior doesn't get warm for awhile, even after driving 20 miles. It blows warm air but it seems like it should be warmer. I've also noticed the temperature gauge barely moves, if it does at all. Most of the time it doesn't move or just stays on cold. I did some research on here & thought I would try to change the thermostat, upper & lower hose and the antifreeze. I'm hoping this will heat up the interior better because it's starting to get cold here & fix the temp gauge.

Previously, I had a 91 accord & that would warm up great, even when it was bitterly cold here. What would cause the temp gauge to do this? I'm even thinking about changing the transmission control module because I read on here that could cause the gauges to have wrong readings. The speedo & rpm gauges also seem to have wrong readings, especially in the mornings or when I first drive it. I used my gps & found the speedo to be off by as much as 10 mph. The other item I've noticed is that I only get around 23-25 mpg highway & on my other accord I was averaging 28-30 mpg highway. Not sure if this is related or not but thought the more info the better.

I have done all the basic maintenance-oil & filter, plugs & wires, valve cover gasket, air filter, tranny fluid but have never done anything with the heating/cooling system.

Sierra :: Temperature Gauge Running Low / Reading Cold

Tempature gauge on my 2001 sierra (4.8) has been running low for awhile. The highest it will reach is round 160. It's currently running rough/rich and bad mpg. I replaced the ECT sensor but didn't work. I'm not sure if there are two ECT sensors on this model. I don't think it's the cluster. Is there a second sensor I'm overlooking?

GMC :: Yukon SLE 1999 - Fuel Gauge Incorrect Reading

I have a 1999 GMC Yukon SLE. I've recently noticed that I appear to be running out of gas at the 1/2 tank mark. When I go to fill it, it seems I really do still have 1/2 a tank of gas (so it doesn't seem to be just a bad gauge). As long as I keep the tank above 1/2, everything is well. What might be causing this?

GTI 337/20th Anniversary :: CEL On / Boost Gauge Reading 4 - 5 Psi Under Load?

Car now has about 67,000 miles on it. I drove it from the bay to Lake Tahoe 2 weeks ago, which is when I first noticed the light. I tried to go to a couple of autozone's to get the code read but none of them would do it. I also noticed that now on my boost gauge that i am only reading 4-5psi under load, so its not quite feeling like i'm getting as much power as before. What a common issue is at about this many miles on a 1.8t car? (GLI)

Passat (B5) :: Coolant Gauge Reading Fluctuating When Driving

Have a problem with the coolant gauge on their Passat? The temperature gauge on my 02 Passat sometimes reads normal (190) when I am driving and then all of a sudden it will drop back to 90. My first guess was the sending unit, but the dealer says it might be the gauge cluster too. I would think that if it was the gauge cluster the other gauges would act up too. ?

Prius C :: Fuel Gauge Not Showing Correct Reading?

Driving on my original tank from dealer today from Upstate NY to NYC. On the way my C had 4 bars to begin then went to 3, then 2 after about 90 miles of traveling at avg of about 55mph. I watched the cruising distance go down to 1 but I still had 2 bars on my fuel gauge (and my crusing distance was conservative compared to my mpg reading the whole trip, which was hovering around 58mpg).

The gauge went from 2 bars to one flashing bar in about 1 minute. I pulled into a gas station about 2 miles ahead and put in about 5 gallons... this put the fuel gauge up to 3/4s or about 3 bars above the halfway mark. What gives? I know there are fuel gauge issues but I thought with two bars I would have had plenty of time before I needed to fill up on these roads with these mpgs.

Ford Aerostar :: 1994 - Temp Gauge Reading Low?

It is a garage queen 1994 4.0 AWD with 42,000 miles in nearly perfect shape. Except for the dent in the rear on the passenger side.

I have posted a picture of the dash when going down the road. As you see the engine light is on. It comes on intermittently, pulled the codes, indicated MAF, 02 sensor, running lean/rich. Runs like a champ, no hesitation, still gets up and goes, gets the appropriate gas mileage. I replaced the 02 sensor with the original Ford Part. Didn't cause the engine light to stop going on after about 20 to 60 minutes driving, sometimes it doesn't come on at all.

Could this thermostat be running too cool and causing the engine to throw those codes? Would gladly take it to a mechanic, but seems like it might be a fishing trip with my dollars for them. Next I was going to replace the MAS myself, easily done with the original remanufactured part at a cost of 150.00, 70 for the core, but don't want to chase my tail with these engine lights on when it runs nearly perfect.

Have sprayed the MAF. Checked for air leaks anywhere. Done all the things I could do by just lifting the hood.

So the picture shows the Temp gauge barely touching the N flying down the road at 70 on a level surface, outside temp about 60. Reading the posts says they all run in the cool section of the temp gauge.

So the question is, do they run this cool? Heater works fine and the gauge goes up past the N resting before the O when going up hills on the way to Tahoe. Is this a thermostat problem on a 20 year vehicle with low mileage, or am I going to have to bite the bullet and let the mechanic go wandering through the vehicle?

Passat (B5) :: Engine Temperature Gauge Reading 190 Normally And Then Suddenly Drop To Almost 0

I have a 2003 Passat and the engine temperature gauge will read 190 normally and then suddenly drop to almost zero, stay there for a while then head back up.

I purchased a temp sensor to replace the old but for the life of me I can seem to locate it. I know it's in the back or rear of the engine somewhere.

BTW, the car has the 1.8 engine.

Ford - Mustang :: 2005 - RPM And Gas Gauge Giving Wrong Reading

I have a 2005 v6 ford mustang and lately the rpm and the gas gauge have been misreading. At first the it was the gas gauge that was reading off then the rpm gauge soon after. However, sometimes the rpm gauge will be working right but my gas gauge is just completely wrong. The other two gauges are working just fine( temperature & speedometer) ...

Toyota - Matrix :: 2005 - Temp Gauge Won't Reading Correctly?

I have a 2005 Toyota Matrix with 250k on it. It has run like a champ so far, with the only problem being an ECM recall last year. I have noticed a few problems recently; the heat blows cold air for quite awhile, and the temperature gauge, while not reading hot, sort of fluctuates between normal and a little warm. When the ECM was being replaced, the dealer said the serpentine belt was overdue for replacement, and I know he's probably right about that. He also said the water pump needed replacing, although I have never seen any signs of leaking. This car has been a champ, and I'd like to try and get another 100k out of it if possible. I'm pretty handy around a car, I've replaced an alternator and radiator before, and I'm working on a limited budget, so if any of this is doable by me, I'm up for it.

Ford A/C :: 1977 F100 - Temp Gauge Reading Higher

I have a 77 F100 2wd 302/c4. I recently replaced the rear plate to my gauge cluster after it crumbled to pieces. I swapped all the gauges to the new plate minus the fuel gauge since it decided it couldn't live if livin was without the old plate. I have a gauge cluster out of my 75 and decided to swap in my fuel gauge from that one. I put the cluster in the truck and fire it up for 10 mins or so and everything is working great except the temp gauge isn't moving. I figure it romeo and Juliet with the fuel gauge so I just swap all gauges from the 75 into the 77 cluster except the speedo. Same result.

So I figure its the sending unit now and maybe both gauges were fine to begin with. I put in a new sending unit and now the gauges works but the needle sits on the P in the word TEMP on the gauge which makes me uncomfortable. That's about 1/4 inch or so from being past the end of the gauge. I don't believe the truck is running that hot. The gauge was more or less straight vertical before the swap sitting right at the end of the E on TEMP. Did I get a bad sending unit? Is it a bad ground on the gauge? Was I supposed to take off the teflon tape that came on the threads of the sending unit? I'm gonna try removing that first and see if it lowers the needle.

Ford Excursion :: No Reading At Oil Gauge And Temp Light Is On When Very Cold

I have a 2001 Excursion Limited V10. 146000 miles 2 wheel drive. I have had it about a year and this is my first winter to really have experience with her.

When the outside temperature is very cold and the engine is cold from sitting all night, at start up, the oil pressure gauge reads nothing and the oil pressure/temp idiot light is on. Only does this during the first very cold start up or after sitting and engine getting very cold again.

I can drive just a short distance (2 blocks) and both gauge and light go to normal and stay there for the rest of my drive. I am using a quality 5/20 oil and filter and the level is good. Warmer days it has never happened. Truck runs fine, smooth idle, no "limp mode". She has not had any recent work done. All the other dash gauges read fine.

There is something about really cold temperatures that have to be causing the issue , I think. ??
