Prius (2004-09) :: Check Engine Light Coming On And Off / Showing Code P0420 For Catalytic Converter

My check engine light has been coming on and off and it seems to show P0420 for catalytic converter. The light stays off for about a week and it'll come on for a day or two and off again.

Wouldn't a failed converter stay failed? Can P0420 be triggered by loose/bad gas caps?

Prius (2001-03) :: Triangle / Check Engine Light Popped On When Driving - Code P3006

I have a 2001 Prius with 210,000 miles. The inverter and traction battery were replaced last year. I started getting triangle and check engine lights about a month ago and the scan tool read p3191 p3006 p0300. The car would barely start in the mornings and the dash lights would be dim. I replaced the 12v aux battery today and all the symptoms went away. Driving home the triangle/check engine light popped on again and I stopped at Orielly's to use their scan tool. It now only reads P3006. I called a local mechanic who suggested to drive it a bit and clear the codes because the battery needed to equalize. Is this true?

Accent LC (2000-05) :: Check Engine Light Came On / Code P0740 - Car Started To Choke

while scraping ice off the windshield this morning with the car warming up, it started to choke, engine light came on. Used my OBD reader and found only one code, that being p0740. Cleared the code and all was fine after that, it drives the same way it always has and nothing feels different, revs are the same shifts gears the same. I know it had something to do with the torque converter clutch.

Ford Ranger / B-Series :: Check Engine Light Started Blinking On And Off - Code 327 / 328 And 334

I've got a 1992 Ford Ranger 2.3L with about 240,000 miles on it. The check engine light started blinking on and off pretty regularly so I pulled the OBD1 continuous memory codes and came up with this.

327 - EVP/EPT circuit below minimum voltage

328 - EGR closed valve voltage lower than expected

334 - EGR closed valve voltage high

I can't say these codes mean a whole lot to me besides I've got issues with my EGR valve and possibly the EGR valve position sensor. I was thinking I'd start by replacing the EGR valve.

Ford - F150 :: Check Engine Light Started Flashing / Cylinder 4 Misfire Code

1997 Ford F150 - 133K Miles - 6cyl - 4.2L. This is a truck that gets less than 2K/year put on it. Has had "issues" with worn bearings and holding oil pressure for a few years now. Yesterday, the check engine light started flashing (as opposed to solidly lit) and the code came back as a cylinder #4 misfire (only the one code). The truck was clearly not firing on all cylinders and at idle, ran terribly (couldn't be driven). I just did a compression test on all the cylinders and all measured around 140-145psi except the #4 which read almost 170psi. I rechecked this a few times as well as a couple of the others and am now sure of the results. What could cause this one cylinder to have a higher compression ? Is whatever is causing this increase in the compression, also be the cause of them misfire ?? I'm stumped here and quite frankly, expected the compression on the #4 cylinder to be really low as opposed to the others.

Honda - Odyssey :: 1995 - Check Engine Light Started Coming On Every Time Drive On Highway

Recently the check engine light has started coming on every time I drive on the highway. At approximately the 5th mile of my ride, the light comes on but I cannot detect any symptoms, the car runs great. This rarely if ever happens when driving in the city, only on the interstate. My car is too old to be hooked up to the fancy diagnostic machine. What I should check to resolve this problem? 1995 Honda Odyssey with 279,000+.....

Santa FE SM (2001-06) :: Transmission Started Going Into Limp Mode And Causing Check Engine Light To Come On

2002 Santa Fe, 2.7 AWD

The transmission has started going into limp mode and causing the check engine light to come on.
The codes given are p0750 and.... I think p0751, for shift solenoids C and D. There is also the generic Transmission Control Module code.
Limp mode only occurs at higher speeds although shifting feels a little rough at times in lower speeds.
If operated in manual mode the vehicle can be driven normally at all speeds without going into limp mode.

Fluid levels are fine.

With limp mode occurring in automatic but not occurring in manual mode, is it more reasonable to believe the solenoids are malfunctioning or the control module itself? I'm inclined to replace the solenoids but find it odd that the vehicle operates normally in manual. Also, can the solenoids be replaced without removing the transmission? It looks like I could get the pan off but am unsure if there is room to get the work done once it is removed.

Volvo - V70 :: 2005 - Check Engine Light Keeps Coming On / One Code Was Consistent

I bought a 2005 Volvo V70 with 75,500 miles on Nov. 13. On Nov. 15, the check engine light went on, and I returned to the dealership for a solenoid replacement. The check engine light went on again on Nov. 17, oil pan replaced. On Nov. 19, the light went on again, timing belt replaced. On Nov. 22, the light went on again. Each time the code was the same--sometimes in conjunction with other codes--but one code was consistent. We returned the car on Nov. 22 and asked for a refund in keeping with the Massachusetts lemon law (an attempt at repair 3+ times). The dealer refused, saying the check engine light and computer code were not the same as an attempted repair. He took the car and said he was going to call Volvo Tech in. However, he says the light "went off" and never came back on even though his staff has test driven it 170 miles in the past three days. He's "releasing our car" to us, even though he has made no repair. Tell me--is trying to address the same computer code considered a "repair"?

Mitsubishi - Lancer :: 2004 - Check Engine Light Coming Up Every Now And Then / Code P0421

My car's an 04 Mitsubishi Lancer ES, 4-cyl, 2.0L. So long story short, my check-engine light has been coming up every now and again for the last couple months with the code P0421, which a shop has confirmed I need a new manifold catalytic converter for (they ruled out any problems with O2 sensors).

Golf IV / Jetta IV :: 2001 - Engine Would Not Idle Correctly / EPC Light Started Coming On

I purchased a 2001 Jetta and it ran alright for a few days then all these problems started arising. The engine would not idle correctly and then a week later my EPC light started coming on. After all of that I have replaced the Throttle body ( Bosch) the MAF ( after market) and gas pedal ( after market). It ran fine for a day and then same issues. I had a mechanic relearn the throttle which had the Engine light go away for about a day. Now all the issues have came back. Here are the main problems.

1. Randomly lose throttle ( up hill, down hill, highway does not matter)
2. I randomly get stuck in park and cannot shift at all.

This is extremely troublesome since every time I lose throttle i have to put the car in park, shut her off and turn her back on to be able to drive. I keep getting the Throttle and MAF codes. I also checked on the recalled parts and they have already been replaced. I have read many reasons as to what would cause this but even the mechanic doesn't even know and I cant pay for him to check the electric. Also when driving if it is raining my car will not start or when it does it chugs. I was running through a puddle and after the water splashed the car basically would no longer run.
