SOURCE: Code #P0171 & code #P0174

The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.

SOURCE: i have error codes p0156 p0161

  Check the wire harness near the top of the engine in the rear. They were good for rubbing through on the trans fill tube bracket. Judging by the code you have 4 sensors. you would be interested in the drivers side rear sensor.

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

SOURCE: location of O2 sensor in bank 2, 99 5.4 expedition, running lean

I have a ford 2003 windstar that was running very rough when cold and almost stalling. engine light came on. went to autozone and they read the codes for free and told me it was running lean on Bank 2 also. i came home searched for the O2 front sensors online using the info autozone gave me. there are 2 front sensors on my car that need to be replaced at the same time. look for ones that have a direct plug in and don't need wire splicing. the ones without the wiring harness are cheaper but more of a pain, i think.
they were fairly easy to replace. getting access with the wrench was the worst. reset the light by disconnecting the battery for a few minutes. seems fine now and the light hasn't come back on.

I had a trouble code of P0340 changed the cam sensor and the pcm,the crank position sensor checked out fine ,also changed the coil pack . now I'm not getting any codes but no start


check all wiring and connections --or ECM connections
the codes refer to sensor A bank 1 did you replace the correct unit

Engine cut out while driving, won't start.


Lets start at the beginning.
If you have a V6 engine you have two cam sensors. And the problem could be the cam sensor(s) is not in sync with the crank sensor due to a problem with the sensor or the timing belt.
Code 340 is for bank one sensor one. You could have as many as 4 sensors depending on which engine you have.
The mass airflow meter code could keep the engine from starting.
The cruise control problem could be related to the cam-crank sensor issue or something else.
You should only have one crank sensor and it is usually near the crank pulley in the front of the engine.

My 96 ford ws 3.8 flashes code 52 also #4 cyl misfire i replaced coilpack, sparkplugs,sparkplugwires,egr valve, diff.feedback pressure sensor and i still get misfire in the #4 cyl. it runs good at first...


Yes. The Code 52 means the O2 sensor on Bank 2 Sensor 1 (Before Converter) has high resistance. These sensors can have a heating element in them to get the temperature up to 750 degrees which is suppose to help detect the fuel ratio in the burnt exhaust gases more effectively.

The sensors have a ground and are controlled by the ECM or PCM. Since your overdrive switch is affecting the operation of #4 cylinder, the PCM-powertrain control module connectors or wiring also uses a ground to make the O2 sensor work with the PCM supplying power. The switching occurs inside the PCM.

The problem with #4 cylinder may be related to the O2 sensor shorting the PCM. Replacing the O2 sensor before the Bank 2 converter would be a good start. Then check the wiring and connectors and ground for both the Overdrive switch, PCM, and O2 sensor. You want to have the wiring straightened out before changing the PCM and frying the new one.

I hope you have found my solution very helpful in solving your problem. Remeber to clear the trouble Code after installing the new O2 sensor.

I have a 1996 honda passport V6, the car was scanned and found code p0134. the car runs but after a few minutes of warming the car stalls and backfires runs terrible what can cause those type of problems


This code refers to the front oxygen sensor on Bank 1. Basically the oxygen sensor is inactive.

DTC P0134 - 02 Sensor Circuit No Activity Detected (Bank I Sensor 1)

The powertrain control module (PCM) provides a baseline voltage of about 450 mV on the oxygen sensor signal circuit. When cold, the PCM detects the the internal resistance of the sensor is high. As the sensor warms up the resistance is lowered and it starts producing voltage based on the oxygen content in the exhaust. When the PCM determines that the time it took for the sensor to warm up is greater than one minute or that the voltage is inactive (not reading outside 391-491 mV it views the sensor as inactive or open and sets the P0134 code.

Potential Symptoms: One or more of the following may occur:
* Check engine light illumination
* Poorly running/engine missing
* Blowing black smoke
* Poor fuel economy
* Dying, stuttering

Causes: A code P0134 may mean that one or more of the following has happened:
* Bad O2 (oxygen) sensor
* Bad heater circuit in the O2 sensor
* Wiring or connector to the sensor frayed / broken
* Blown heater circuit fuse
* Holes in the exhaust system
* PCM failure

Possible Solutions: The most common fix is to replace the oxygen sensor. But that doesn't rule out the possibility of:
* Rusted exhaust pipe
* Inspect wiring & connector(s) for problems
* Excessive amperage blowing heater fuse (still requires replacement of sensor but also replacement of blown fuse)
* Replace PCM (only as last resort after all other possibilities are covered.


Hope helps (remember rated and comment this).

How to fix po134 sensor


O2 Sensor Circuit No Activity Detected Bank 1 Sensor 1

the bank one sensor is either disconnected are faulty.

the bank one sensor is the sensor in the exhaust of the rear cylinder bank of the engine cylinders 1,2,3, the sensor is the one before the catalytic converter. U will need an O2 semnsor socket to remove it or in some cases a 7/8" open end wrench will do.

Error code po340 for a 2002 hyundai elantra


Here is what I could find on your P0340 error code:
CausesA code P0340 could mean one or more of the following has happened:
  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • the crankshaft position sensor may have failed
Possible SolutionsWith a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required
Sounds like since you have replaced both the camshaft and crank shaft sensors you need to look at the PCM.  Go down the line of possible solutions and don't replace the PCM unless nothing else works obviously.  I hope this helps but it looks like you are looking at getting a new PCM.  Good luck.  Thanks for rating my response and for using FixYa!
