Could a speed sensor connection just be loose causing a trac light flash plus check engine code?
no, trac lights have to do with traction control, this is part of the A.B.S system, what are the codes that are stored, you could check the connector for corrosion or loosness but I need more info to help.
Your Chevy s10 wont start it turns over but doesn't fire you just a snow storm and it is all gone now what is wrong?
knock sensor is a very sensitive small microphone usually on the engine block or sum times on the cylinder head , it listens for any pre detonation going on in your engine . pre detonation is nasty early combustion you dont want, if you get pre det it causes a pre knock sound which the knock sensor microphone detects. your probly not getting pre detonation but thats what the sensor does 8) "sensor 1 circuit"…
2002 civic si check engine light Code P1298 air fuel Metering How much is this going to cost im guessing this is the mass airflow sensor?
A 1988 Corvette with a 1986 engine Tuned port injection From a stop light excelerating in the beginning does fine then falls on its face?
Could be a number of things, the first thing I would check would be the TPS (throttle position sensor)The sensor itself could have a bad spot which would mean replacing the sensor, also check the electrical connection at the sensor. Second would be to check the connection at the MAF (Mass Airflow sensor). Other things to check would be fuel pump, fuel filter, fuel pump relay. Good luck
It means barometric pressure out of range. Could be caused by: Bad vacuum line or connection between intake and sensor Bad sensor Bad connector or wire between sensor and computer a plugged air filter A plugged exhaust system An engine that runs poorly enough to send this sensor out of range. The sensor has an "allowable range" that it can be at for a running engine at certain throttle and loads. If it gets out…
What else can be wrong if your engine light is blinking if its not the cluster or the speed sensor could it be the alternator your car died on the road a couple times Can anyone help you out?
a check engine light that flashes while driving has nothing to do with the speed sensor or alternator a flashing engine light shows that there is problem that is causing catylitic conver damage for instance if you had a bad spark plug or spark plug wire that was causing a missfire then the light will flash there is no other reason for the light to flash
My misubishi 3000 gt engine light comes on and engine dies and won't restart just cranks any ideas what is causing this?
If the engine light is coming on at the same time as it the engine dies and I am guessing it starts again. It may be your electric fuel pump. You left too little information about the sympton as it could be a number of things. The check engine light will come on if the engine dies. it could be your o2 sensor
Could it be a bad oxygen sensor after the car warms up causing a problem that a 1993 Tempo rattles shakes and check engine light comes on but does not do on short trips around block?
Had the same problem - could be either the gas tank cap is not tight, and not sealing airtight, or it could be a bad oxygen sensor in the engine, causing the air/fuel mixture to be off. Went through this with my '98 too. I had the O2 sensors replaced to pass emissions and it came back on.. I probably have a problem with my intake valve, running too lean and tripping that sensor.
What is causing 2001 Saturn sl1 to have a sudden hesitation while driving only when car is cold and at a slow speed?
I have answered a lot of these questions. Just goto AUTOZONE, and ask for a Free Trouble Code Check ( aka DTC or OBD). It could be bad spark plug, bad spark plug wire causing a misfire in a cylinder. Could be a bad 02 Sensor. Could be bad fuel (water in fuel) could be running rich. MAF Sensor (Mass Airflow Sensor). ANy number of things really. Just have them scan your car. They will…
Your problem appears to be sensor-related. Could be one or more of these sensors: Throttle Position Sensor (TPS); Mass Airflow Sensor (MAF); Intake Air Temperature Sensor (IAT); Idle Air Control Sensor (IAC); or other sensor that affects engine performance. It would be wise to take your vehicle to an auto parts store that does free diagnostic scans (ie. AutoZone, Advance, O'Reilly's, etc.) to find which sensor is causing the problem.
It could be a number of things. But, I would start with the Mass Air Flow(MAF) Sensor. That's what happened with my '96 Suburban. When you open the hood. It's located in between the two coil hoses that run from your air filter to the motor. Start up the engine and pull out the plug. If the engine changes idle then it's probably not it. But, if it does could be the source of the…
That is a code for 'Front O2 sensor open or short.' This could be as simple as a loose or bad wiring connection at the front O2 wire harness, a problem with one of the fuel injectors, an intake air leak or even low fuel pressure. If you are having higher than normal fuel consumption and smoke at exhaust, possibly the O2 sensor is dead. The front heated oxygen sensor (or O2 sensor 1) is…
Tough question,untill you find out whats causing the miss to start with. Could be 1 of these problems making it miss. ( Bad spark plug, plug wire, Bad distributor cap, Injector problem, emission sensor shorted are grounded- O2 sensor / oxygen sensor, Map sensor, vacuum leak, Low engine compression / burnt Valve. ect....
Could be anything from a spark plug! to a spark plug wire, a sensor, transmission etc. You would have to go to a shop and have them connect the OBII computer to it or you could go buy one for about $100, and even if you bought one you would then have to understand the codes it gives you, could be more than one thing causing the check engine light to come on.
1998 Chevy Malibu 3.1 engine-V6 has no spark Replaced cam sensor crank sensor idle control sensor and still have no spark could it be the computer?
I had my check indicator light on and the first time is was a sensor that controlled the amount of fuel going to the engine, it failed and was starving the engine of fuel. I had to have the sensor replaced (expensive) Second time it was the Oxygen sensor that goes into the flexible exhaust pipe. The pipe had developed a leak and was causing the sensor to go off. I had the pipe replaced…
You have replaced the map and air flow sensors in your 1990 tbird v6 when the air flow sensor is disconnected the engine runs better but the idle is low what could be causing the engine run rough.?
With the sensor plugged in does the engine have problems while driving at normal operating speeds? Is the problem just at idle. Your IAC (idle air control) may be bad. Go to autozone.com to pull up a picture and location of it on your vehicle. You can also unplug this to see if your idle levels out.

What causes the temp gauge to flutter when you come to a stop on a 1997 Mazda 626 the engine kind of shakes at a stop and it flutters. i changed the temp sensor any ideas?
it could be a list of things, the most common is possibly a short in wiring to the ecu or engine harness. It could also be possible that your engine mounts are wasted and allowing your motor to shift and torque causing sensors to tug loose (OR) it could even be pulling the wiring the other way from your ecu.
What would cause the upstream oxygen sensor on a 95 Dodge Neon to keep going bad in less than 1 day?
Several things could cause an O2 sensor to get bad that quickly. First, it could be bad wiring that is causing the signal to be incorrect, meaning the the sensor is still good but it is bringing back bad data. Two, if you have any cylinders misfiring this could cause raw fuel to be pushed down the exhaust, causing the sensor to foul. There are always lots of other things that could be happening that…
