OBD-II Code Troubleshooting BlazinTex 11-19-02  
96 S10 Blazer 4x4. Getting OBD-II error code of P0102. MAF low voltage. Chiltons full manual used to go into detail as to why this would occur on Pre-1996 or OBD-I codes. ANyone have any ideas?
PO161 Bank 2/Sensor 2 Chad Lee 6-8-06  
Have a 97 Ford Explorer 4.0 SOHC with 120,000 miles. Engine light came on and had it tested. It shows PO161 Bank2/Sensor2. I replaced the oxygen sensor and had the code reset. Got two miles down the road and the light came on again. Had it reset for a second time with the same result. I also replaced the DPFE sensor by the valve cover. Please help with this guessing game. Thanks for your time. Chad

1996 Ford Ranger Code Troubleshooting J. Rojas 2-11-03  
I am seeking information on the following codes:

1.) P1443 System Control Valve. What do I need to repair/replace in order to clear this code?
2.) P0125 Insufficient Coolant Temperature for Closed Loop Fuel Control. What do I need to repair/replace in order to clear this code?

Please respond to "jvr4210@swbell.net" before Thursday.

I thank you in advance for any help here.
Re: OBD-II Code Troubleshooting TKO 12-7-02  
First of all, Chilton sucks. The factory service manual is always best. Next step is Mitchell or All Data.

The Freeze Frame data will tell you alot, so look it over carefully to see what the conditions were when the code was set.

Test the MAP according to diagnostic procedures. This will include checking the ref voltage, applying vacuum to the map with a DVOM, sensor ground...

A build up of corrosion or errosion around the MAP sensor reference, signal, or ground connection can cause a voltage drop, so check these lines with an ohm meter to insure good connections.

The first step is to plug in the Scan tool and check the MAP readings with key on engine off (koeo). You should get 1.5-2.5 volts. If it is below 1v, there is something wrong. With the engine idling and hot, the voltage should drop. Puch the throttle and the the voltage should rise.

If everything checks out, there could still be a problem. Again, check the freeze frame data and try to duplicate the problem.

If you can not find the problem, erase the code and see if it returns. You have a 96, so this first year of all OBDII standard vehicles may set some interesting codes...

Re: OBD-II Code Troubleshooting sebastain 1-17-04  
I replaced the charcoal canister assembly with new valve, and sensor from my local for dealership for a 1997 Ford Ranger 4x4 3.0L the part # was F5Z2-9C987-CA and it was about 100.00 on 1-17-04, I dont have a reader so since I replaced the part that was giving me the P1443 Code, How do I erase the code so I can get it to pass inspection?
Re: OBD-II Code Troubleshooting Robert Orr 7-7-05  
I tried to get my 1997 Ford T-Bird inspected today. It failed the OBD II test. They said the MIL Commanded-On failed. The codes given were PO135 - 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1), PO141 - 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1), PO155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1), and PO161 - 02 Sensor Heater circuit Malfunction (Bank 1 Sensor 2). I have a V-8, dual exhaust T-Bird. Can you please tell me what the problem is and possibly send me a schematic showing where these sensors are located by email? I would like to try and replace them myself, since they are somewhat expensive. Thanks!

Re: OBD-II Code Troubleshooting patrick 10-5-09  
My check engine light came on a few weeks ago & I had the computer scan indicate that it was either my egr valve stuck open &/or my egr pressure sensor failed.

I replaced both & reconnected my negative battery terminal & drove my car for approximately 8 miles at about 55-60 mph.

Stopped & put about $10.00 of gas in & as I drove away, the service engine light came back on. I took it for another scan & it is saying the same as it did before I replaced the EGR valve & EGR sensor. The troubleshooting Error Code is PO402. There is no indication of any problems with the hoses connected to the EGR Pressure Sensor.

How to I ccorrect this problem & how do I properly reset the cars computer to correct these errors.

I have been given to different sets of advice:

1) is to simply discinnect the negative battery terminal &

2) is to simply drive the vehicle for 50-100 miles to reset the computer & correct these problems.

Please help! Thank you in advance!

Re: OBD-II Code Troubleshooting robert 12-5-06  
Engine service soon light comes on, had it checked and advised it was # 174.

one automotive service said it could be a problem thats somewhat easy to fix but that it would cost about a $1,000 as something that goes down both sides of the engine may need to be replaced.

the car is a 1996 lincoln cont. with a 306ci ( or whatever ) engine.

your thoughts.
Thanks
Re: OBD-II Code Troubleshooting Cliff Porter 12-4-06  
I have a 1999 GMC Z71 4x4 extended cab 1/2 ton truck the ABS light has been on for over a year, every thing still works ok, but when I tried to correct the problem with the OBD-11 code reader it did not give me any information and it would not correct the error or reset the light on the dash. I have had the rotors and brake shoes changed before putting the reader on. Unless I still have a problem with the sensors it should have reset. Is there something else I may be missing? I have read several truck repair manuals but have not found anything, and would appreciate any advice. Thank You.

P1443 code on 97 ranger the evaporative emissions contol valve....find your charcoal canister then folow the hose towards the intake manifold...first piece of equipment is the valve next in line is the sensor...the valve is a solenoid plunger type valve that can gum up causing it to stick...remove it from the vehicle and clean it with some carb cleaner if possible jumper 12 volts across the 2 pins to excercise the valve...I did this and no light in the last 4500 miles....

Re: 1996 Ford Ranger Code Troubleshooting rick brice 4-29-03  
I fixed a P1443 code on my 1996 ford ranger last week.

1)Chilton Sucks... This code has to do with the vapor recovery system and the vapor canister and the vapor valve and the vapor sensor all located on the lower drivers side of the engine compartment..... and its not listed, pictured or talked about in Chiltons.
Ergo, Chiltons Sucks!

The valve is of extremely poor quality.
The hoses are of extremely poor quality.
Ford tried to sell me the wrong valve.
Make sure you get the right one.

I bought a kit from ford with all the parts from the cannister to the intake manifold for $99 + tax.

Problem solved... I still have a serviceable used sensor if I need it.

Re: OBD-II Code Troubleshooting Bruce 3-26-06  
You can get a code that indicates a problem but its not serious enough to trip the check engine light. Look for that sensor from the Catalytic convertor rearward.

Re: OBD-II Code Troubleshooting Jessie 5-14-08  
Have you triedchanging the o2 sensors? the are located along the exhaust and are sometims difficult to take off. They are mildly expensive, but can result in drastic changes bettering your gas mileage
Re: OBD-II Code Troubleshooting Alan S 2-21-08  
It may be the sensor but I have seen it be bad battery cables or dirty connections. Clean all battery connections and make sure the battery is good. Other thing is on cold days turn on the key and wait 10 seconds before starting. what you are doing is trying to pre-heat the sensor.
