Faulty MAF?

**rocky.ca** · 10-18-2008 09:23 PM

I VAG'd the G/s and at WOT i record 103 g/s I am assuming that this is a little low. Could it be due to a clogged air filter? The readings arent eratic, it just stops at 103gs at redline... Also, i have the code 17521 - Oxygen (Lambda) Sensor: B1 S1: Internal Resistance too High P1113 - 35-10 - - - Intermittent does this mean that my O2 sensor is bad, if so what one?

not sure on the MAF but you need an 02 sensor. Thats the first one or the one closest to the turbo.

Not necessarily. Clicky Click. I ordered replacements for both 02 sensors from him. The only issue is they do not come with the connector, but it has plenty enough slack for you to just splice them into your existing harness and seal with shrinking tube. This is considering that there is nothing wrong with your connector and it is the sensor itself which is faulty. And yes, they are brand new Bosch units (no, I do not know why there is no connector sent with it. but for the price why ask).

When I purchased mine, he had a lot more in his inventory. So, I did not get the Universal ones as he had the specific ones for my vehicle in stock at the time. I paid like $55 for the secondary 02 sensor and maybe $28 for the primary.
