View 2 RepliesGolf IV R32 :: Air Mass Meter Signal Too Low
Started the car about an hour ago. Pulled out of the driveway went about 15 feet up the road. Noticed the dashboard light with the (!) was illuminated and I didn't even turn off ESP. Shifted to about second gear power cut off engine shut off.
Pushed the car back into my driveway scanned it with VAD.

edit: car idles higher than normal. sounds like MAF is toast?
Ford Ranger / B-Series :: 1993 - Getting 157 / 158 And 159 Codes - Mass Air Flow Voltage?
Truck is a 1993 ranger 4.0 ohv
Ok I have been getting 157, 158, and 159 codes. I have cleaned and replaced the MAF with no success. I checked the voltage to the sensor 12v, checked the voltage from the signal wire and it is to high. It has been high on the cleaned unit and on both replacements, so I am thinking it is not the MAF, but what will cause it to register high. I cant get the signal voltage below 1.9V at idle.
Signal also reads high with the ignition on and the engine off. What would cause the voltage to be high, I have read it could be an IAC but I would think that would not effect it with the engine off.
Touareg :: Voltage Meter Zero And No Turn Signals
Has there been any definite solution to the problem of the voltmeter going to zero immediately after the Touareg starting up and loosing the blinkers, including the hazards. When the vehicle is running in this mode all the other electronics are working fine, I tried them all. The vehicle runs normally, just the volt meter at zero and no blinkers. Has happened three times in two and a half years. I would take it to the dealer but it wouldn't do it there and they would just tell me it is working fine. What can I do, or even tell them to fix it.
View 3 RepliesBuick - Parkavenue :: 1995 - Red Light On Beside Voltage Meter Comes On Intermittently
Most cars have either an idiot light or a volt meter. This 1995 Buick Park Avenue has both in the same pod. The customer complains that the red light comes on intermittently, but the voltage continues to read just above 13 volts. Sometimes it's dim or flickering, others it's bright. It seems to be more prevalent when the headlights are off, rather than when it is under a heavier load with them or the A/C on. I have not had an opportunity to see the car. It has not failed to start.

The brief information:
1. Stuck/non moving in traffic on the freeway for roughly 1 1/2. During that time the AC was running, but once I noticed my "battery light" on the dash turn on, I turned everything off.
2. Since then while on my way home from work the voltage meter only showed barely 12 volts at full throttle.
3. I charged my battteries, and started it up today to go into work. While going to work the voltage meter showed 14 at its high point, but shortly there after it dropped back down to 12. At which time the battery light came back on.
New battery or alternator?
Golf IV R32 :: Intake Air Temperature Sender Signal Too High / Air Mass Meter Signal Too Low
I drove to the mall and left the car there, when I was done and tried starting, it fired up but the rpms started to fall and CEL came on. CEL are:
-16497 P0113 050 Intake air temperature sender-G42 Signal too high
-16486 P0102 050 Air mass meter-G70 signal too low
And after it died it cranks but never fires up. I called the dealership trying to find out where the IAT sensor is but they said it's in the manifold and not sure where. Where is IAT sensor?
Lexus RX 2010-15 :: CEL On Indicating Check AWD System / TRAC Off
My 2015 Lexus RX 350 has been indicating "Check AWD system, TRAC off" for sometime now. It all started when I overfilled the tank and it spilled over. The indicator came on after about 12 hours. What may be responsible. The car is barely 6 months old and don't know what to do right now.
View 4 RepliesFord Fuel System :: Location Of Check Valve That Maintains Fuel Pressure On The System?
I have a '99 E-350 6.8L. Where is the check valve that maintains fuel pressure on the system?
I have been experiencing a starting issue when the engine is hot. Cold starts are usually fine. I've replaced the in-tank fuel pump (pump only, not the assembly) to no avail. I was out of town and didn't have access to a fuel pressure gauge when the problem started so I couldn't say what I had prior to replacing the pump. But now, with a new pump, when I check pressure, I get about 40 psi when I first cycle the key on, but it drops right back to zero as soon as the pump shuts off. If I cycle the key on a few times, sometimes I can get it to hold pressure at about 32 psi, and it starts fine. When I shut if off, it goes back to zero psi, sometimes gradually, like a bleed down, and sometimes immediately.
My conclusion from this was that the check valve was bad. I was told it was part of the in tank fuel pump assembly. Since I didn't replace the entire assembly, this made sense. So I just dropped the tank back down, but I don't see anything as part of the pump assembly that serves as a check valve. There is a rubber nipple on the end of the return line, but I don't see how that can hold any significant pressure.
So, before I go out and spend another couple hundred bucks on the complete fuel pump assembly, which apparently can't be purchased without the actual pump, I thought I'd ask. Where is the check valve that holds the pressure in the fuel system?
BTW, I also have replaced the fuel rail pressure regulator, but it made no difference (I went there first since that was much easier than dropping the fuel tank a second time).
Prius (2004-09) :: Loud Gurgling Sounds Indicating That There Was Air In System
I took my 2007 to the dealer yesterday to have spark plugs replaced and both coolants drained and filled. They did this in less than 2 hours. After the service, as I started driving away, I heard very loud gurgling sounds indicating that there was air in the system. When I stopped at a light, the gas engine did not shut off like it normally should, and the entire car was shuddering. When I accelerated again, I got a bunch of emergency lights and the gas engine shut off. I pulled over and turned the car off. When I turned it back on, the only remaining warning lights were the red triangle of death and check engine light. (I didn't see which other lights came on, as I was frantically trying to pull over safely). I managed to limp back to the dealer and I'm awaiting their call.

Suspect I have a bad fuel pump. I checked for power thru the Inertia Switch. When I first energize the ignition I receive 12v after a couple seconds it drops to 7v. Is this normal? I checked at the connector to pump module and see the same reading. I swapped fuel pump relay and same readings. Just want to makew sure I dont have some other issue before doing pump.

Getting volts to #30 fuse 30amps ok, voltage to pcm diode ok. Voltage on #30 on both relays(pcm & fuel) but I am loosing voltage across coils contacts #85 & #86, these makes hot #30 & #87 to make pump work. Inertia sw ok, Don't know if PCM is bad, ck fuse #2 ok 5 amps.
Ford F-150 - 1997-2003 :: 1998 Truck Not Starting / Not Getting Voltage At Fuel Pump
I have a 1998 Ford F150 with 4.2.. Started off a intermittent problem of not starting acct no fuel. Now will not start at all. Checked all fuses and relays.. Am not getting voltage at fuel pump. Changed ECM thinking that was the problem.. Have checked all multi wire connectors for corrosion and tightness. Am at a lost what to try next.
Also, not sure if its related or not. The turn signals and hazard flashers do not work. When I turn on the hazard flashers, nothing happens. If I leave the flashers switch on, the turn signal work. Checked all fuses and relays and they appear good.
Jeep - Commander :: Check Engine Light Comes On Steadily / Not Flashing Indicating Poor Quality Fuel
My Jeep Commander 2006 (a problem vehicle until i had it repaired/much replaced by non-dealer service center, i.e., i know that these are 'finicky' cars on their best days), the engine light comes on steadily/not flashing indicating poor quality fuel. It did this 60mi after this last fill up at the gas station, and it did so after 60mi following the previous fill up. The engine light then goes off -as Jeep told me it would - after driving it about 60-70miles. this happened a couple of times last summer as well. I've tried going to different gas stations in the area thinking different stations would have different fuel suppliers, but what i noticed is that BP and Sunoco for example are getting delivery from same truck. ?: how can i determine quality of gas before I put it into tank? I always put in premium but it doesn't matter what the label says if the quality isn't any good.

I went to move the 2000 yesterday and it will not start because the gas went bad. It has been sitting about 6 months, since it did not snow this past winter. How do I go about cleaning the fuel system? I was thinking suck the gas tank empty with an electric fuel pump, and blowing out the lines with air. Does this sound right?

I have a 2005 accent that keeps blowing the ecu 1 fuse. It is also showing a code for "system voltage low", and the battery is wet around both posts. I read somewhere else that the alternator could be surging and blowing this fuse. Had both alternator and battery checked at autozone, battery is said to be on the way out and alternator shows its fine. Battery does not show any problems, start car just fine.
