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 RepliesSo I just replace my Cat. Converter with all new sensors in them. I just replaced my spark plugs. (I'm knocking out these check engine light problems) and I think I'm getting close to the root as to why these other parts went bad. Why my o2 sensor would be stuck on "lean" ....
View 5 RepliesSo 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.
Just checked SES code and read P0162 I think. Stated rich fuel mixture bank 1 & bank 2 (3.0) Is this an O2 sensor or MAP issue?
View 8 RepliesI have a P2195 and P0171 ... 2006 Ranger 2.3 ... Drives fine but at idle..idle gets slower till it lopes. Changed O2 sensor,Cleaned air flow sensor,changed PCV valve, Can't find any leaks, could it be EGR...how do I check it ?
View 1 Replies2007 camry xle 4 cylinder engine, 2.4 liter I'm getting a P2195 code, which is the A/F sensor B1 S1. I have a few questions:
1. Any diagram of the location?
2. I've been trying to figure out the correct part number, so I can search for a replacement. I've found 4 or 5 different numbers already. What is the correct part number?
3. Should I only by the OEM part? Or do the aftermarket brands like Denso work?

Okay getting ready to trade in my Truck. So I removed all the extra things I put on there while I was in college, the amp, fog-lights, and analog oil pressure sensor along with their wiring. It was pretty easy minus removing the oil pressure sending unit part.
I had to unplug the MAF to move the intake out of the way while I was repairing a loose vacuum tank. But I forgot to plug it back in when i closed everything up. I started the truck and drive it about a half mile before I was able to pull over and plug it back in. Truck ran and shifted fine after that, but the CEL came on. P0119 Coolant Temp Signal Intermittent. Guy at Autozone said it was Intake Air Temp Sensor intermittent and I could just replace the part, but they were showing a separate part even though it is built into our MAFs.
So now the CEL is on, can get it to go away. Truck is a little jerky every once in a while, like a misfire, when between 50 and 60. Before all this the CEL was off. Now after I cleaned it up and removed some of the superfluous accessories, I get a CEL. I wanted to trade it in this coming weekend without having to take a loss because of the CEL or spend more money to fix it.
So I had a post up saying "is MIL P1444 a urgent fix" and I got "no". On an other website though it said that it was an urgent fix. They said it was "similar to running a bad catalytic converter. You don't want to do it."
P1444:
Possible causes
- Faulty Purge Flow Sensor
- Purge Flow Sensor harness is open or shorted
- Purge Flow Sensor circuit poor electrical connection
So I located the purge flow sensor and look at the tube that connects to that,the canp solenoid, and the carbon canister. Nothing looks bad, but I did notice that the tube that connects to the carbon canister to the solenoid is not connected. The part that connects to the carbon canister dry rotted off. So I turned on my car to see if anything was coming out of that tube or air and there was nothing (not sure if that's good or bad). Also a week ago when I filled up my gas tank (before the check engine light was on) a lot of fumes were coming out of the tank while pumping.
The scanner i use also lists the secondary air system, the EVAP system, Heated catalyst, and the AC refrigenant has red X's, but they weren't continuous.
Got a code of p0708 on 2003 ranger flex-fuel 3.0.. Which is I believe is Transmission Range (TR) sensor. Not sure where to find that on truck...
View 1 RepliesAny resource that I can use to find the part number of the O2 sensor on my wife's 03 v6 Camry.
I have a check engine light, scanned by code scanner to reveal P2195. This OBD code is supposedly sensor 1, bank 1 "stuck lean" which is the upper O2 sensor on the left side of the engine (closest to radiator with transverse mounting).
So it should be easy to change if this is the issue but I'm having a hell of a time finding the right part number. Too many choices.
I have a p2195 trouble code with my 2007 Toyota Sienna CE. This is O2 Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1. I am assuming I'll need to replace this sensor. It's a little confusing but if I am reading my Haynes manual correctly, the repair goes as follows:
The sensor for 2007 and later models will be in the exhaust pipe after the catalytic converter. To remove it, it's necessary to remove the passenger seat, disconnect and snake the pigtail through the grommet in the car floor. Then, disconnect the O2 sensor from underneath the van and replace.
I just bought a '98 Ranger 2.5l 2wd. After driving it for a week or so I got a P1405 Code. After a quick google search I got :
P1405 Ford - DPFE Sensor Circuit Upstream Hose
Possible Causes: - Faulty Differential Pressure Feedback Electronic (DPFE) sensor (EGR pressure sensor)
- Plugged or damaged EGR tube
- Differential Pressure Feedback Electronic (DPFE) sensor harness is open or shorted
- Differential Pressure Feedback Electronic (DPFE) sensor circuit poor electrical connection
Now, I have done my research between forums and youtube and have found this EGR system to be quite. I've gone ahead and replaced my DPEF. I took an air hose and blew out all the small lines coming into the DPEF. I still have the engine light. My next move is to get a volt meter and see if I'm getting power to the sensor.
My question is about this particular code and is it possible I need to look farther into this EGR system (EGR Valve, EGR Hose, etc.)
1999 Ranger 4x4 4.0 - P0135 O2 Sensor Heater Circuit (Bank 1 Sensor 1)
I have replaced the 02 Sensor, Passenger Side (Pre-Cat), with a Motorcraft DY831...
I reset the Check Engine fault codes, and took it out for a 50 mile journey... Check Engine light is back on, with the same exact code... What next?
I understand that it may be a fuse, and/or it may be a short in the wiring... Exactly how to test the wiring from the connector at the 02 Sensor all the way back to wherever I need to test?
I really need detailed directions, like wire colors, voltage required, or ohms, or whatever is included in this process...
I have a 2006 Ford Ranger with the 3.0L v6. The check engine light came on and the code it is blowing is a P0171. It runs rough at idle or when I let off the accelerator and "fine" at speed.
The code told me to check/clean the MAF which I have done. Next on the list that I saw was the PCV valve. I disconnected the electrical to it and then disconnected the hose. Some oil poured out of it... not a lot but some... The valve still seems free, it clicks when I rotate/shake it and I can blow through it (I know, highly scientific). I can replace this (if I can find it, Napa and Advanced Auto don't have a part that looks like it...) but I'm wondering what else could be wrong.
I just bought a new truck. Its got some...well hacking done to it.
Previous owner did some "stuff" to the o2 sensor wiring.
Also installed a cat back new exhaust.
Should there be another O2 sensor after the final cat?
Problem: engine surging/hesitation, from idle to highway speeds. It will start and run fine, just hesitates/surges when gas is applied.
Before I pulled the codes, I tried seafoam in the gas tank, cleaned MAF sensor, cleaned throttle body, checked air filter, changed fuel filter, pulled/cleaned plugs, nothing worked.
Then today I finally used a scanner and pulled codes (my CEL doesn't work) and I got 157 and 158 MAF sensor fault, high and low voltage. I am reading about 6v on the C and D terminals of the MAF, I know that is much higher than normal, but what does that tell me? Why both high and low voltage readings? Just a bad sensor, or wherever that voltage comes from, ECM?
I also pulled 189 HEGO H02S sensor fault, unable to switch/lean during part throttle. What does that mean, just a bad O2 sensor?
Last I pulled a 542, fuel pump secondary circuit fault. Does that mean the fuel pump is bad or going bad?
More importantly, what should I troubleshoot first, would any of these codes cause my problem?
Where the temp sensor for the rear view mirror is located. My truck is a 2011 Ranger with the 4.0 liter, AC, automatic and 4x4. I think it is somewhere by the headlights but not sure.
View 6 RepliesMy check engine light came on about a week ago and was unsure what the problem was. So I tested the codes and it said that the camshaft position sensor was bad. So I have tried finding this sensor but little to no luck. I was unsure if it was the 2 or 3 pin, but after looking at some pictures of the engine I'm thinking it is a 2 pin. I attached two pictures of what I think might be the sensor? But I am unsure. This was right next to the timing belt cover, which is where it said it was located. I have a 1996 Ford Ranger, 2.3L.
View 6 RepliesI removed what I could, plastic cover and thermostat housing. Looks like I have to pull the intake to get the little bugger out of there. What's the procedure to remove and replace?
View 2 RepliesI have a 2009 Ranger 2.3 L manual with about 100000 miles. The engine was bogging down and I just found out that the MAF sensor is bad from testing it. In the process, I measured my fuel pressure to be 73 psi (manual says 60-65 psi). So I have two questions:
a.) Is there any chance of just cleaning the MAF sensor. The sensor has zero volts when running and warm (or .02 v) and barely changes when reving the throttle.
b.) Perhaps then the high fuel pressure is an unrelated issue. Is this so high that I must change the regulator as I have to change the pump as well? Might it be some other issue than the regulator which is what the Hayness manual says?
One theory I had for the high fuel pressure is that the bad MAF was leading to bogging and lean conditions and the computer was running the pump more to compensate but I think the computer might run the pump based on fuel pressure not the o2 sensor.
acts like abs sensors could be bad. but the brake pedal goes almost to the floor, after it does it's pulsating. But the abs light does not come on. I already changed brake booster, no change!
