    I would start out by replacing the throtle body control sensor and the idle air controll sensor. I think this is your tickent but I would do a complete tune up also plugs wires and distributor cap and rotor if you have one.

    let me know how this works for you.

    the idle air control sensor is next to the throtle body, very close to the throtle body sensor.

Is the wiring good going to the O2 sensors? Maybe just look the car over and see if you have any bad grounds. They can do weird things. Could be a bad ICU.

I have five codes P2237 P2196 P2271 P0030 P0171 and a P2237 pending code on a 2005 elantra.The car runs poorly, bad gas mileage, sluggish with the check engine light on.Are all O2 sensors bad or maybe the...


P2237 P2196 P2271 P0030 P0171

These are all O2 sensor trouble codes, except P0171 which is a fuel trim code,

You have a bad 02 sensor - up stream - Bank 1 Sensor 1.

Replace it, then road test. The engine computer has a 'default' fuel trim it uses when an O2 sensor fails so it can protect the catalytic converter. If this hasn't been going on too long, good chance simply replacing the O2 sensor will remedy your problem.

Trouble codes p0171, p1131, and p0136


p0171 = system too lean bank one. p0136 is a bad Ox sensor bank 1 sensor 2. You have at least one bad Ox sensor. 4df0849.jpeg

P0136, P1131, and P1151 codes on Ford Expedition 2000 4.6L


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.

I get engine light, borrowed neighbors DTC reader get code P0136, could bad gas cap cause the eror?


P0136?

Yes this can be caused by the gas cap lack or week rubber.

Rate this and replace the gas cap.
