22 mins ago - SOURCE: check engine light is on...bank 1 sensor1 oxygen sensor. if u have one .... 2.7L dodge stratus/ #1 bank #2 sensor location? on 2004 Stratus. Oct 24 ... How can I set the timing on a 1996 dodge stratus 2.4l engine.
One suggestion I have is that each of the new type of engine's have an O2 sensor which is part of the exhaust. This is used by the computer to measure the amount of O2 in the exhaust gasses in the exhaust.

02 sensor circuit low voltage ---answer is copied from obd-codes .com you can visit this site for more information if necessary Usually rear o2 sensor problems won't cause drivability issues since they are an input that measures catalyst efficiency (unlike front o2 sensors). However if you have other codes present, like lean codes or pre-o2 sensor codes, then they may cause drivability problems as well as P0143. The following symptoms may be present: MIL (Malfunction Indicator Lamp) illumination Engine performance issues Engine running rough Engine running rich (only if PCM is trying to add fuel to compensate for low o2 sensor voltage reading) Engine running lean (only if vacuum leak is large enough that PCM can't compensate by adding fuel) Poor idle Causes If you have reason to believe that your engine is running lean, fix that problem first, then clear codes and see if the P0157 code resets. An engine that is running lean could set this code, but usually there will be lean codes (P0171, P0174) present. The following could be causes: Air leaks in exhaust in front of o2 sensor giving false reading Engine running excessively lean O2 sensor connector damaged/corroded O2 sensor signal circuit is shorted to ground O2 sensor ground circuit is open O2 sensor has failed (it may be contaminated with fuel or coolant) PCM has failed
Hi I am looking to find out if anyone else agrees that the metal part of the o2 sensers are the same only the plastic connector is different. So if you buy the up stream senser that is cheaper than the down stream one and splice your old connector to the new metal senser you have a fix.
check your O2 sensor and wires other thinks that can cause that problem is when the engine is running in close loop. u should check if the other codes have to do anything with the coolant system. u should fix the other codes first and see if the p0157 go away.
