Definition of Diagnostic Trouble Code P0171
Category:
Powertrain
Definition:
System Too Lean Bank 1Note: This definition of P0171 is applied to all manufacturers
P0316 crankshaft position sensor, camshaft position sensor, or a wiring issue. Since this code indicates a start up misfire, pay attention to items which may expand or contract when cold (if the code sets when the engine is cold), or hot (if the code sets on a hot restart).
If you have other misfire codes that pertain to individual cylinders, you should attend to them first P1151 has a huge list of things that it can be, But included in that list is the camshaft position sensor , po1131 is the same thing, all building up to your car is running lean , so I'd do the sensor (cam) and check timing,,
P1131 Lack of HO2S-11 Switch ,Sensor Lean
P1151-Lack of HO2S-21 Switch ,Sensor Lean
PO171- System to Lean (Bank 1)
PO174-Systen to Lean (Bank 2)
Fuel Filter -Plugged

O2 Sensors-worn out
Your auto has four O2 sensors. Two upstream and two downstream; With two banks. Bank 1, sensor 1...and bank 2, sensor 1 are the two upstream (exhaust manifold before the catalytic). Bank 1, sensor 2 and bank 2, sensor 2 (other side of catalytic)
Code 1131= upstream; bank 1..sensor 1 Code 1151= upstream; bank 2..sensor 1 Code P0136 (generic code) bank 1..sensor 2 (questionable)
I wouldn't spend the money to purchase 3 sensors. Highly unlikely all three are bad; Cost is about $40/ ea. Since there isn't a code for the cat's themselves, I would suspect the O2 circuit is malfunctioning. The rough idle is another clue.
Take an ohmmeter set it on X10 scale and measure the resistance from engine to body and body to negative post on battery terminal. You should read zero ohms (full needle deflection). If you do go buy two upstream O2 sensors. If you read open or a high resistance run two straps from eng. to body...and body to neg.batt. post.
Try to pin point, (if not already) what the other codes are for. How does the truck run while idling and driving. Also, if the code for one sensor is showing then it's best to go ahead and replace it - it may be bad due to another issue (or code that has shown up as well) and chances are, you'll need to replace the second (if equipped) O2 sensor.
po301 thru po306 all misfire codes cylinder 1-6 remove plugs and replace them..... set the plug gap first
i suggest u replace the wires also if they never been replaced all these misfire codes can set the others and one is for the oxygen sensor ( 02s or HO2S) CIRCUT MALFUNCTION do u know how to check wireing systems
do the tune up plugs (set gap) .052-.056 change the fuel filter also. clear the codes hows it run
this info is for 98 E-250 4.2Litre
what engine do u have 4.2L or 4.6L i know it is a v-6 by the codes
