need to get it checked before i change the maf sensor to make sure its guilty....can you buy a tool ? what should the afr be ?? 1996 gtb..

Wideband sensor and dsiplay is required. I suppose you could check the voltages from the MAF against known values.

rabskyline

too technical for me that....can i get a gauge and wire it in?? will this tell me if its the maf thats guffed ??

A Wideband AFR will not tell you if your MAF is Broken, your ECU can tell you if the MAF is faulty, you have to connect the two wires which are just under the dash (drivers side), if there is a problem your CEL will give a series of Flashes.

i know about the cel process mate but there is no cel and fault codes as the mafg doesnt show up on this process.... i bought an afr and need to wire it in...also spoke to local scooby specialist and he said that maf's are famous on these cars.....

Maf's are a known weak spot....... but not on your model year,later versions 99/00 are prone to fail,yours should be very robust...... what are the symptoms to make you sspect the maf?

You can't just wire in an 'afr' you need to weld a boss into the exhaust, fit the sensor into that and then plug and play the readout.

I'm sure i've seen ones that take there readings from the existing sensor?!?

The rookie

Indeed, but the reading is gumpf from a two point sensor as that has a very steep responce curve through circa Lambda one (most are actually symmetrical about Lambda 1.02) with them reading their reach or lean voltage but within less than 0.05 Lambda.

If you plug them into a wideband sensor they will make a bit more sense!

Ah, so. Existing sensor narrowband?

simon (jgm) reckons its the boost solenoids or hoses. but i am going to fit this gauge anyway...ive cleaned out the hoses and i will take her a run now...where can i get a ecu pin diagram...

rabskyline

afr gauge fitted and all is ok that way..but i must have put a wrong hose on now as i aint getting boost and fault codes 66 and 32 !!!! turbo system and o2 sensor !!
