2005 jeep grand cherokee Po204 205 175 174 138 158. Runs rough. Whats wrong?


PO204,205 are injector circuit malfunction,PO174 is a system lean code, PO175 is system rich code, PO138 is heated oxygen sensor bank1 sensor 2 circuit high voltage, PO158 is heated oxygen sensor bank2 sensor 2 circuit high voltage. This is a repair for your mechanic. When they fix the injector and o2 circuits the rich lean codes will also be repaired. Continued driving will ruin your catalytic converter. Good luck

Po171 and po174 oxygen sensors for 2002 Chevrolet Silverado 2500hd w/6.0 litre engine - truck has 12 - how do I find out codes?


your truck should only have 4 o2 sensors two upstream and two down stream. P0171=system too lean, P0174 I= bank2 sensor1

4 Codes in computer


code p0128 indicates a mechanical fault ( could be the thermostat stuck open)
code p0174 -system too lean -bank2 ===causes --intake /exhaust leak--fuel pressure/pump--injectors--AIR system--hose connection/s
code po171 refers to system too lean bank 1 same as po174 with the HO2S sensor being the culprit. As to all being related . only by way of the o2 sensors
code p0442 is not connected to the first 3 as it is in a different section of the fuel system

2002 eord F150 po174 system adaptive fule too lean bank2


PO174- too lean bank two --is a possible rich
condition driven lean by the pcm

Check for leaking injectors,vacuum leaks,fuel pressure

Look at fuel trim on scanner

The front oxygen sensors get replaced every 100,000 miles,
so there may be some of the problems

Start with fuel trim,cylinder misfires,spark plugs, injectors, on that
bank, as a place to do your testing for the code

Look at freeze frame data & I/M Monitor activity, to see if the O2
Monitors ran clean & look at O2 data

WHAT ARE THESE 2 COMPUTER CODES FOR MY FORD RANGER V6 4.0 WHAT ARE THE PARTS THAT NEED TO BE CHANGED TO REMOVE AND FIX THESE CODES, CODES ARE PO171 system too lean bank 1, and PO174 system too lean bank 2


Description : The adaptive fuel Strategy continuously monitors fuel delivery hardware. The test fails when the adaptive fuel tables reach a rich calibrated limit. Now that we have an Idea of what the codes mean , we need to narrow them down. More than likely the problem is causing both codes to set. Keeping this in mind, lets concentrate on Code PO1309. Of the possible causes listed above I see two Sensors that may throw up a lean code. I would look at the MAF Sensor first and then the Temp Sensor. You may find that if you remove the internal Sensor from the MAF Case that some degree has collected on the thin wire. If you find debree, use a Q-Tip to clean it. DO NOT USE CHEMICALS TO CLEAN IT. If no debree is found, try a Known Good MAF Sensor. Still no fix, move on to testing the rest of the Sensors on the list till you find the problem. Keep in mind that the check engine light will have to be cleared after you have fixed the problem.
