Ford F-150 (2004-2008) :: Getting P0605 Code Every Now And Then / PCM ROM Error
Apr 27, 2013
I just bought a F150 with 103,000 on it. The engine is a 4.6. I get a P0605 code every now and then which doesnt effect performance. I erase the code and it doesnt appear again for maybe another 100 miles.
I suspect a loose connector but not sure. Looked up the code and it reads PCM READ ONLY MEMORY (ROM) ERROR. My question is what does the PCM operate? And wheres a good place to start troubleshooting?

I recently changed from a problem-ridden SCT Livewire to a SCT Xcalibarator3, and now when running my custom tune I get a check engine light and a error code P0605. I never got this on the same tune with the Livewire. What causes this and how to fix it?

I have the error code P0340 and have changed both camshaft positioner sensors, cleaned the air sensor and throttle body and still the engine stalls. I can accelerate at 40, 50, 60mph and it jerks violently. I tried the "locking it in third" trick but it still jerks. Today I unplugged the left cam sensor and the truck idles @ 400rpms, does not stall, and pretty much drives great! Hook it back up and crank it, within 10-15 seconds it stalls. I plan to check the wiring....

I have two codes off my "digi moto lite" obd2 scanner....
P0201 - internet search suggests it's a fuel injection code....
However I can't find anything on code C3203....

What would make the OBD II not read the code that is set on my truck. It says "Communication Error..." Fuse 41 grants power to the Diagnostics port and the cigarette lighter. The cigarette lighter is working. Any other reasons I can look at?

My 2007 Ford F150 Lariat (5.4L) with 82k miles popped a P0307 (#7 misfire) code one chilly morning. It began stumbing and hesitating a bit between 25-35mph, and each time it occurred, the engine light would flash on and off. Hesitation clears and light goes steady. Cleared the code and didn't see problems again for a month...until the next cold day (freezing temps). Popped again and hesitation returned. Ford dealer wants to change plugs. I've read coils can also cause the issue. Not sure if I can do either myself.

I've had a CEL for awhile so I final had it checked. It is the P0605 pcm memory error. He cleared it to see if it will come back. There isn't any chip or never has been a chip in it as far as I know. If it does end up being the pcm, what are my options? can it be repaired? Do I need a new one? Can I get a used one and if so what are the criteria I need to look for, for it to be compatible?

I got a Ford f150 and getting the error code P0446 Evaporative Emission Control System Vent Control. My truck has burnt up 3 of these things already in the last 8 months. Why my truck keeps killing them?

I have a 2008 Sports Trac, with a 4.0 SOHC engine ... 165k miles. Last week my check engine (CE) light came on and the code is P0401 ... too little flow on the EGR system. I first tried cleaning the existing valve - but CE light still came on. So I replaced the old EGR valve, cleaned the SS tube from the exhaust manifold back to the EGR valve and the CE light is still on. I have not driven the truck since I replaced with the new valve ... only fired her up in the garage. Is this something that could possibly clear up given a couple of miles?

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.

I have a Toyota prius 2008 with 130,000 miles. I kept getting red triangle sign, the car will slow down and will need to pull over, shut it down and restart. I went to the dealer. First they diagnosed 12V battery issue, so we got that replaced. The red triangle sign kept coming, so we went to the dealer again, they replaced transmission fluid. They said it was low on transmission fluid. The red triangle sign kept coming. So we went to the dealer again. They said it is transaxle internal problem. The diagnostic code is P0A37. I have a couple questions. In California, what is the warranty for Transaxle problem. In some posts I saw 180,000 miles, 10 years. The dealer said they called Toyota and Toyota does not cover the repair. It is a costly repair. Second , is this code really requires Transaxle replacement.

I have a trouble with my 2008 prius; red triangle engine light is coming and when i try to push the gas pedal it feels like it's freeze, the car does not accelerate so I have to stop.
After i turn it off and start again it drives ok, but a triangle is still there and there is error code POA90 ( two different scanners show same code with two descriptions; the first is "MOTOR PERFORMANCE"; the second describe it as "14-volt power module system voltage high").
Specially it happens when i drive up the hill and push the gas pedal harder. What it can be? I took the car to the Toyota dealer; they looked for 8 hours and find nothing; i can't do it again as the car do not have a warranty and the dealer charge for hours.

I have a Lariat 4x4 supercrew cab with a CD 6 disc changer head unit. Error message. No Disc, and Load Error. Will not eject any of the 6 loaded CDs. Pulled/reset fuse. No luck. Banged on dash while trying to eject any of the loaded CDs.. no luck. Unit cycles when first starting the engine. Radio works fine. Unit locked up....Ford Mx tech says the solenoid that holds the CD is frozen in position and will not release.

On the way home from my first weekend trip in my '04Screw, I noticed the speedometer did not agree with my GPS, which was sitting ontop of the dash. The speedometer was reading 2-3 mph faster than the GPS.
The truck was taching about 2,000 rpm .. speedometer read 72-73 .. and the Garmin III+ GPS read 2-3 mph less than the truck, tracking 8 out of 12 satellites, and varied between 68 and 69 mph.
My Lariat does have 18 inch tires. I don't have a clue if that caused the difference.

Within three days the alternator and fuse #23 blew. After replacing these and the fuel filter (because of stalling during acceleration), I took it for a diagnostic check at O'Reileys because the stalling while accelerating worsened, it wasn't shifting correctly and the O/D light began flashing on the shifter. It hit on these 13 error codes:
P7055
P0446
P0750
P0443
P0743
P0135
P0141
P0155
P0161
P2195
P2197
P0423
P1747
I have researched each code (definitions, what to examine/test, and the locaton of each part). My question is that with this many hits is it most likely a problem with the PCM, or should I just proceed with checking each connection, wiring and solenoid individually? The EGR Valve tested fine and the alternator is pushing 14.6 v...

2006 F150, 4.6 V8 ... My truck was running fine until one morning I was sitting in the truck giving it my customary 30 second morning warm-up and it starting running very rough and quickly threw Check Engine LED.
I hooked up my laptop and got the following error codes: (To assist with future searches, the error codes are P0302, P0303, and P0353)
It seemed to drive fairly well, but low RPM torque causes major shuddering, so I try to keep the revs up to avoid damaging other components. The first step was to replace the spark plugs. They looked to be original and I'm at 140K on the truck, so it's probably time.
I went with Bosch Platinum as the factory plugs were platinum. When replacing the plugs, I moved the coil pack from cylinder 2 to cylinder 3 to determine if the problem would move. After the plug swap, the engine did run noticeably smoother (so the plugs worked overall), but still had the low rpm shudders and the same error codes (after clearing them).
Unfortunately, the error codes still indicate cylinder 2. I guess a misfire could be related to the fuel injector as well, not firing at the right time or not a complete spray, but what else could cause this?

My car has been fine with no changes besides tires last week, its a 2006 Prius and yesterday I got lights on my dash, went to auto zone for a read out and got an HV error code. I was wondering what is the most affordable route for my car to get repaired. I don't notice any mpg differences and everything still charges and recharges as if the errors don't exist.

I had a check engine light come on on my 2004 G35 and I took it to the dealership to have it checked out. They came back with a code of P1760 and said I would have to replace the automatic transmission valve body. My understanding is that the solenoid valve controls transmission fluid and should be pretty cheap to replace. But I don't know why I would have to replace the whole valve body? My car is not giving me any issues with sluggish shifting when I drive or going into a fail-safe mode where it wont shift into higher gears etc. My question is, should I do what the dealer is saying or do I have better options that will also save me money like buying after market from Stillen etc.

Its a 2009 Prius with about 75K miles on it. I have scangauge on the dash as well as mini-VCI. It is setting PO456 code time after time. I reset it, but it comes back in about 50 mils of driving. Its not the gas cap, I turn it until it clicks every time. Something is wrong with evaporative emissions system, which I wouldn't care about, except it might mask some other fault code that is more serious, as it keeps check eng. light on all the time.
