My 96 4x2 2.3ltr is throwing this code (P1443). I clear it and it comes back a few cycles later. I will fix it next but won't be able to get to it for a couple weeks. What if any affect does this code have on fuel mileage and or engine performance/power?
View 3 RepliesWhich one is the ect? One is the ect and one is a switch for something?
Just gone done switching that POS plastic thermostat housing thing, both sensors were replaced not sure which one is throwing the code.
I have cleared the code and it keeps coming back.
So here is what I got. Code 157 maf sensor below minimum voltage. Here is what the truck does. When the MAF is plugged in and I step on it, the truck surges and when it drops below 1k rpm it dies but I can start it back up. If I hold the throttle at 1k it stays alive. When I drive with the MAF unplugged it runs better no surging but it still dies. Here is what I have done. Reset codes no change, put new MAF in no change. I have traced all 4 MAF wires checked continuity from inside of plug to inside of plug.
All wires checked out good. No cuts breaks or anything. I have checked my battery, starter, and alternator ad all check out fine. I read that someone said if the corresponding transistor in the PCM took a dumb then it would cause not enough voltage to get to the plug because the transistor would dump the voltage from the battery leading to the MAF. I thought about running a direct power source from the battery to the voltage side of the MAF with a switch in the truck to just see if that would solve the issue but I don't know if that is possible or smart.
I have a 1997 Ford Ranger with a 4.0L 2WD. The check engine light just turned on with a code of p0133. I know that this is something with the bank 1 sensor 1. I tried doing some research and I think that it is on the passenger side before the cat converter. Now, I don't know what to do from there. How do I go about fixing this? What part do I need? How do I fix it?

View 8 RepliesI am having an engine issue with my 1995 Ranger with a 2.3L. I have been having a P0340 code that kept appearing after several attempts at resetting the PCM. I gave up and took it to a Ford dealer for diagnostics and they called the CPS bad. They changed it, but the CEL light immediately came on with the code still kept coming up. The service rep. showed me the old sensor, it had a spot on the head of it where it looked like something was rubbing it. I'm assuming it's slightly rubbing on the gear it points to, which is the oil pump gear, correct? The truck runs fine, no performance issues whatsoever. Is it possible my oil pump shaft has developed play in it's shaft, causing this?
View 1 RepliesI've been getting this code for a while. Changed the Purge solenoid and valve, replaced the hose from the canister to the two units, didn't change the hose to the intake.
Is there anything else to check? Could it be a bad gas cap? the one on the truck is a replacement.

Just bought this truck. When I test drove it no "check engine" light came on, but after purchase driving home is came on and then off many times. It only comes on at high rpm/speed. I have my trusty ODBII scanner but realize that this 1994 was pre-ODBII. How can I figure out what the CEL is about?
My son has a 99 Ranger where the airbag light is flashing code 32. I had the same code on my F350 and it was the clock spring. What it could be. It is 99 Ranger with 2.5l, auto trans, 2wd, no CC.
View 2 Replies2008 Ranger 3.0L. I am trying to figure my next step in diagnosing a #4 misfire. At regular speeds I really dont hear it or feel it, mostly at idle warm or cold. 3.0L with 275,000 kilometers on it , reg oil changes.The CEL is on, but not blinking. Pulled a p0304 code. I then changed out the bosch plugs I had in with ford plugs and wires. The #4 plug looked okay just bigger gap. Still got the code.
I hooked up a sparkplug light to the coilpack and did not see any missing flashes . Changed fuel filter, checked fuel pressure,all within specs. Changed the oil and did not see anything in it. I read that it could be an injector but I have to remove the intake manifold to get at it. I also read to check compression. I figured if I have to take off the manifold I would put a new injector in, instead of switching them around. What is the most common cause for this code?
Today my Check Engine Light came on for the first time in years on my 1998 Ford Ranger. It has 363,000 miles on it. But the engine was changed about 150,000 miles ago. It's a 2.5 automatic. It runs good and has no problems until today. I was leaving a shop and when I started up the truck the Check Engine Light came on. It wasn't idling bad but when I went to take off it wouldn't hardly move. I wasn't even able to keep driving. So I stopped and turned it off and restarted it. Then the Check Engine Light was gone and it ran fine. I scanned it when I got home and it a Pending code of P0446.
I've never gotten this one before. It said something was wrong with the fuel vapor vent solenoid open or shorted. I've never replaced anything on the evaporative emission system except a hose under the hood 3 or 4 years ago. I've had to change the fuel pump a couple times. I've never had any wiring issues. I've never hacked into the wiring. I've owned it since it was new. Is it likely that solenoid is failing or the vapor canister is shot? I don't need this to happen again because even if it's in what was called limp mode. there's no way I could've driven it home like that. I couldn't even pull over. I was lucky I was still in a parking lot.
So... p1451. Vent solenoid. I pulled the part and put 12v to it. Opens/closes just fine. Checked resistance on part, 55ohms like it should. Pulled vent canister, no apparent leaks or blockages. I traced wires back to cab. Cannot locate anybroken wiring. I looked up the pinpoint test on this dct and all thats left to test out is the pcm itself. Before I buy the obd2 scanner with all modes I wondering if I am missing something.
I did find a broken ground wire in my searching. Frame to body. My thoughts on a bad ground are that that would cause more than one monitor to register one fault code.
I have a 1997 Mazda B2300 with 175,000 miles that has an intermittent check engine light. When I check the code it is always P0420. If I leave it alone long enough the light usually goes out. The truck had the catalytic converter replaced about 5 years and 60,000 miles ago. I also had the muffler replaced in October, but I was getting this code prior to the muffler replacement. I recently bought a scanner that can monitor the fuel trim data and noticed that the long term fuel trim is generally between +16 and 18%. I replaced both oxygen sensors last week and cleaned the MAF sensor, but today I got the CEL again. The LTFT is also still the same as it was before I replaced the O2 sensors. My truck doesn't use any noticeable amount of coolant or oil and I'm not really sure where to start.
View 8 Replies I have 92 ranger with 3.0 v6 in it.
It flashes out code 212 ive replaced the ICM and checked the spout connector for corrosion but it still flashes out 212 and has a rough idle no power on acceleration condition.
also when the idle starts acting up the check engine light stays real dim and if you rev it it will get brighter
I have a 2006 Ranger 2.3l 4 cylinder that is have emissions problems the code the tech gave me was P2195 an I bought the o2 sensor just where it is, and the auto stores didn't have a manual for the year of my truck.
View 2 Replies2000 ranger 2.5 stick, coming to a stop i put in the cluch and the motor speeds up then slows down sometimes more sometimes less.
A month ago I had a code PO171, with a good idle. I cleaned the MAF senser then cleared the code, a week later the the CIL came back on same code. Then a month after the CIL is on the engine idle problem started. So I recleaned the MAF with MAF cleaner, cleared the code, and replaced the ICV with a new one. That worked good for about 3 days now the idle problem is back again.
The idle problem seam to be worse when the motor is warm or has been running at freeway speeds.
99 2.5L. P0455. I'll just be driving and the CEL will come on and stay on. I pull the code and get a P0455. Gas cap is brand new and I can wipe the code and it will come back a few days later.
View 2 Replies2004 3.0 auto 2wd. ABS light (and brake light) both on solid. I got the code C1186 - ABS power relay output open circuit pulled today at oreilly. He said there were no codes for the brakes. So, where to start and could it throw both lights for the same code?
View 2 Replies'92 Ranger 2WD, brake and light inspection revealed the warning light isn't coming on. I guess there is a light that would come on in the instrument cluster either when the e-brake is on, or there is a problem in the system. The shop guy says often junk just builds up and prevents it from working; guess I will remove it to clean it up first. Guess it could also be a burned out bulb in the cluster. My Haynes book isn't very good on this.
View 8 RepliesI have a 1999 ford ranger 3.0 6 cyl with 211,110 miles It started running rough without any previous warning signs. In idle its barely noticeable, once i put it in gear it gets rougher and when driving around 40 to 45 mph it roughly shakes and shimmies. Once I get past the 40 to 45 mph range it settles back down. Is there a specific issue that would cause that at that speed. When going up over a bridge the check engine light blinks.
I changed the spark plugs and new wires and it offered no success even though one of the plugs were black (to much gas). I have borrowed a diagnostic tool and got P0305 cylinder 5 misfire, I am thinking fuel injector to replace, what else should I be looking at?
