1996 E320 P0130 code.....driving me nuts!

I have sold a couple of my cars recently and just purchased this car, the car had code P0130 bank 1 sensor 1 O2 sensor. Seeing the age of the car I replaced both o2 sensors with new bosch units direct fit. I have a fairly new reciept where the previous owner replaced both converters so that has been done. I can clear the code and everytime around 4 or 5 miles down the road the check engine light pops on every time with the same code P0130. What could my problem be since I have just replaced the 02 sensors and my code is for a faulty o2 sensor? Car runs and drives just fine at all times. I can't get it inspected until I can get this CEL resolved.

the problem with codes is everyone assumes if it's an o2 code it must mean it needs an o2. the code means the ecu doesn't like what the o2 is doing. it's true of every code. get it diagnosed or buy a day at startekinfo.com and diagnose it yourself. good luck, chuck.

99% of the time P0 130 means a bad sensor.

You could have the other 1%?

Is the car a 1996? for sure.

Code P0 130 is not in any listing for a 1996 car.
It is a valid code for a 1997 car.

I would check and re-check every vacuum hose for any potential leak.


Reference:

The O2 sensor produces a voltage based on oxygen content in the exhaust. The voltage varies between .1 and .9 Volts, .1 indicating lean and .9 indicating rich. The ECM constantly monitors this voltage while in closed loop to determine how much fuel to inject. If the ECM determines that the O2 sensor voltage was too low (less than .4 Volts) for too long (for more than 20 seconds (time varies with model)), this code is set.
Usually the cause of P0130 is a bad oxygen sensor, however this isn't always the case. If your o2 sensors haven't been replaced and they are old, it's a good bet that the sensor is the problem. But, It could be caused by any of the following:

*Water or corrosion in the connector
* Loose terminals in the connector
*Wiring burnt on exhaust components
*Open or short in the wiring due to rubbing on engine components
*Holes in exhaust allowing unmetered oxygen into exhaust system
*Unmetered vacuum leak at the engine
*Bad o2 sensor
*Bad PCM

MB Doc.....I meant to get online earlier and let you know, after some checking today I removed the sensor called the local foreign auto parts store that I purchased the sensor from and found out they sold me the wrong unit, they had the right one in stock and I installed it. It took care of the problem.......I hate to think I went to the trouble of checking so many things and taking so much time when I just needed to back track. Thanks alot guys
