So I have a check engine light on and it goes off and on randomly and when I checked with a scanner at like pepboys it shows code P0420 which is the catalytic converter . [URL]....................
View 3 RepliesJust had my lexus dealership do the ELF recall. While it was in there I had them check to see why my check vsc light comes on randomly which sets off the check engine light.
They came back and told me that my water pump is leaking, what are the future problems of a leaking water pump?
They said the check vsc light is coming on, in their words is "found center y pipe, gaskets leaking at front pipe, may still need to replace converter pipe." So what does that mean and what do I need to do?
First, my g/f and I love her 2.0T, but lately a few things have started to bother us.
1. Strange, rhythmic squeeling at low speeds (like a bearing or warped rotors) that goes away when the brakes are applied.
2. Driver's seat is rocking back and forth under heavy acceleration and braking. I hope it's just a loose bolt and not a crack in the floorpan.
3. Check engine light randomly comes on for a day or two then goes off conveniently after we schedule an appointment with the service department.
What might be causing these issues?
I have a 2001 Ford Focus ZX3 (2D Hatchback) that has been randomly stalling since we bought it. There is no engine light, the dealership couldn't get it to stall and just gave it back. Another garage got it to stall and thought it might be the "idle-oxygen sensor" (not sure if I'm remembering the name correctly), but that didn't stop it from stalling either.
My wife is ready to dump it, but even spending a couple thousand a year on repairs is less than the grand total of a year's payments on a new car, insurance, etc. But it would be nice to fix it.
Ive got a '94 ranger with the 8 plugs and more often than not while driving and sometimes when it first starts, the cel comes on and immediately I notice a lil rough running and lack of power. Also my milage has dropped since this has started. Plugs, wires, o2 sensors, not to familiar with my gas saver. I love it cause I can just get in it and go. With twice the fuel milage as my bi truck!
View 14 RepliesI randomly started throwing a couple codes that have been causing my "check engine" light to come on ... came on on my way into work this morning) . I know that the P0683 code is the Glow Plug Ctrl Module to PCM Comm Circuit (from my code reader), but I am not sure what to do next ... I have the dealer service DVD from 2002 that I will look at this weekend....
View 7 RepliesSo my wife was driving our '10 escape xlt and the engine light came on and it displayed the 'check engine' message on the screen. It has 86500 miles and luckily no problems yet. The only thing that has changed was she accidentally put super premium gas in it the other day. The light came on and after she drove it home (about 10-12 miles) and it sat for a few hours and i drove it about 20 miles it randomly went off while it was idling.
I shut it off and let it sit for 20 minutes and then let it idle for a few and it never came back. It has been running ok. We definitely drive it a lot as she works day shift and i work nights. I'm just trying to make sure there's nothing wrong with it. I got a bulletin a while back about the intake getting moisture in it. I didn't know if maybe this could be the beginning of this or something else. This is a whole new territory for me as i consider my 91 f250 'new'
So after installing my JoeZ axle back for about 5k miles I noticed there was an issue. The check engine light was going on but turning off randomly. I finally decided to take the car to the dealer for them to check out. So what the dealer said is that the JoeZ exhaust "direct bolt-on bolts" restricted flexibility and caused leaks in the front cats. He said that the stock exhaust screws had the springs on it to allow flexibility when hitting dips/potholes. With that said, He recommended switching the front two gaskets and using the stock "spring screws."
I was wondering, encountered this problem with the bolts that came with the JoeZ axle back? I bought the JoeZ off a user here and it came with bolts, which i assumed came with the exhaust when it was purchased new. Not even sure if the bolts he gave me was correct, or if i just made the mistake of not using stock bolts.
'95 LeSabre, 250K, runs great. Check engine light on randomly and signs point to a computer malfunction causing the light to come on. Is it true that only a dealership can replace the computer, not an indy mechanic? How much for the repair? Will it run ok w/o a new computer?
View 6 Replies2000 Ranger 2wd 3.0 ... I bought my truck last summer for $1k from my neighbor, it has hit a deer so the grill is busted,front drivers fender bent up and bumper is bent all to heck. The old girl is rock solid reliable though and gets decent mileage with cruise heat and ac so I'm happy.
Anyways on to the point, I am having two big issues with it, the check engine light randomly comes on and causes it lose power sometimes at others you don't notice it. I have not been able to get codes read because it goes off every single time I go to someplace with a scanner. The light will usually go off if you floor it for a long stretch maf maybe?
The other issue is the transmission, I don't know for sure which tranny it is but the overdrive button does not work at all even though the fuses are good and when I drive down the highway second gear you have to let off for it to shift sometimes ( I've been leaning towards the valve body gasket for that) and lately it has started a horrible vibration kicking out of overdrive or just downshifting on hills etc.?
I forgot to mention it has 255k miles on it and I don't know the history besides the balljoint I replaced this week and radiator when I bought it.
The check engine light keeps coming on and off on my 2001 Echo with the above code. The car runs fine and the check engine light randomly comes and goes. What would set off the check engine light, but not cause noticeable change in performance?
View 2 RepliesI own a 2000 Ford F-250 5.4 Automatic. It tows my 5th wheel trailer very good. On our last trip it suddenly experienced the "check engine light" effect.
The light turns on randomly and either goes of after a couple of seconds or it doesn't go on when I restart the engine.It is mainly annoying, but when in towing it really hurts, because the engine switches into an emergency mode and stalls.
I read that the engine uses only 4 cylinders. I read many articles on the web about that light, but I couldn't find a solution. The thing is I brought the car to several repair shops but none read a code from the computer.
I think it's not a real fault but a misreading or maybe a cable that's grounding? The problem is, I can't bring the car to a repair shop, because there is nothing wrong with the car. How can I find the source of the problem?
My 2011 Camry LE 4-cyl has 48k miles. Today I was driving on the highway during very heavy rain. My vehicle slip indicator light came on, along with my check engine light. I stopped at Advanced Auto for a diagnostic check. They said they couldn't be sure if it was a sensor, or maybe a wiring issue.
View 3 RepliesI had my oil and air filter changed and tires rotated yesterday. within an hour of driving time my slip indicator light and check engine light are on! What the problem is?
View 3 RepliesVehicle is a 2003 SLE 3.0 L 1MZ-FE V6 Automatic. Problem: Check Engine Light on & TRAC Off Light on. AutoZone diagnostic produced three codes, P0155, all referring to Bank 2 Sensor 1. Was told downstream however after ordering matching DENSO part and then taking said part to a mechanic to install, mechanic tells me AutoZone diagnostic was incorrect. His diagnostic was telling him the malfunctioning O2 sensor was upstream, not downstream. Yet he did not tell me if it was left or right bank. He told me to find out from AutoZone or Advance Auto Parts?.I just want to make sure I get the right 02 sensor so I don't have to go through having the incorrect part installed again then removed just so I can return it to get the correct part. I've been told my car has three sensors, two up front, one underneath. I am aware it is best to get DENSO over Bosch.
View 3 RepliesI installed my i-throttle but I might have done some steps wrong don't remember exactly but now my check engine light is on.I throttle works fine. Is there a way to fix this and make the check engine go.
View 2 RepliesMy sister has a 09 camry le I4 and on her way home her VSC Trac off and check engine light came on. What the cause is ( she checked the gas cap )...
View 4 RepliesI just had a new header installed (deletes first cat) and had my header back exhaust redone with high flow resonator and cat. As expected it eventually threw up my check engine light, I am assuming because the poor computer is utterly confused by what my 02 sensors are telling it. I was thinking tuning, but I am not sure where to find a tuner for the camry, or which tuners would work on the camry computer.
View 5 RepliesI have a 2002 4 cylinder Camry, and I've been having trouble with the EVAP test completing. I've been running the EVAP test to the letter, with no success, so I figure the problem might be dependent on something else not completing.
I used to get the occasional check engine light for loose gas cap. So a few days ago I intentionally left the gas cap VERY loose (it's essentially just sitting in the filler nozzle). But I'm not getting the check engine light. I think that the gas tank pressure test may not be running, and that may be why I can't get the EVAP test to complete successfully.
Conditions: The gas level is about 1/2 full, and the ambient temperature has been around 20-35 degrees F.
I'm having a hard time searching. Most search results deal with how to resolve the loose gas cap problem. The check engine light is not burned out... it comes on briefly when I start the car!
I have a 2000 Toyota Camry that has a unique problem. The Check Engine light NEVER comes on even when first starting the car. I have access to a scanner and know that the car periodically throws a catalyst code but the light never comes on. I just assumed that the bulb was burned out.
Today while solving a non-working clock issue I had to take the instrument cluster to get to the clock. While I had it out I decided to check the Check Engine Light bulb. It looked fine so I took I replaced it with a bulb that I knew worked fine. Again, nothing. The bulb doesn't light at all. About 4 weeks ago my timing belt broke while driving (non-interference motor) and it threw a code for the camshaft position sensor but again the light never came on.
Why the light never comes on?
A few days ago I noticed a whining noise coming from the engine and thought it was the power steering unit or the alternator. I was going to bring it in to the dealer this week but last night while driving, the check vsc light and the ABS light came on momentarily and then went off. Then it happened again and again until the lights began to dim and the engine started to shudder. So I quickly started driving home and saw the speedometer going from 0 to 60 mph, the headlights were practically off, the power window would not close, the console lights alternated from dark to lit repeatedly and the car was bucking as I sped home.
I knew the car was running on the battery alone and it was now very low.When I finally had to stop at a traffic light it stalled and would not start. After waiting 20 minutes for a tow truck, I tried to start it and it started. So I immediately drove approximately 3 minutes to a Service Station near my home and parked it there and then canceled the tow truck. Does this sound like the alternator went bad? I should also mention that yesterday before this whole incident took place, while I was stopped at a light with my food on the brake I noticed the brake pedal depress ever so slightly. I didn't think much of it because I knew I had an issue with that whining noise and was going to bring the car into the dealer Monday.
