Error codes




Last week I finally got around lifting "T-Rex's" hood to check on my passenger side xenon light. It has been playing up since several months now, by sometimes not turning on. Solution was to cut the light switch and turn it back on. Sometimes it would take several attempts to get the bulb working, but always worked.
Well, it finally decided to stop working completely, so I pulled it out and switched the driver's side bulb to see if the ballast was working on the blown side and it does. Good, so no expensive electronics to purchase. I ordered two new xenon bulbs as I am certain that after I change one, the other will blow shortly after. I did not get them from the dealer but ordered through a reputable electronics web store which I use from time to time. I was still flabbergasted to see the price quoted of approx $240 equivalent
. Jeez that's getting expensive.I was also started to experience some misfire and hesitation from the engine when accelerating from idle. This was only from idle and not further up the rev range. Got out my smartphone and suitable scanner application (Torque), pulled the codes and found the following:
P0100 Powertrain - Mass or volume air flow sensor
P0500 Powertrain - Vehicle speed sensor
P0150 Powertrain - O2 sensor circuit, bank2 sensor1
OK the P0100 shows the MAF to be the culprit, so I ordered a new Bosch MAF which I have just installed.
The code P0500 pointing to the vehicle speed sensor, I can't figure out why the code is registered and everything works perfectly (tempomat, speedo,... No warning lights on either apart from the blown xenon bulb (see above). Anybody have an idea?
Code P0150 points to an O2 sensor. Bank 2 sensor 1 meaning what and which side?
Thanks peeps




O2 sensor & BAS/ESP & Speed sensors, are almost mysterious systems in our W202, they looks like demons and always thought codes to the ECU/data file memory,
it will shows in OBD/ or STAR, but that doesn't means you got faulty with them, don't worry,,
just delete them from ECU memory, and reset the whole system..

ZAYED,,
