Does anybody have a cheat sheet or good starting point to check the most important measuring blocks for a 1993 Eurovan?
I've just done some maintenance, and I'd like to check some data against expected values.? I have a Bentley, but to be honest, I can barely make sense of it most of the time.

'93 is pre-OBD II!
Utilizes 'Blink Codes'...
To read with an OBD II code reader you need an adapter OBD I to OBD II... and an OBD II code reader that bothered to decode the Blink Codes.
the Ross-Tech VCDS is the only unit I'm aware of that bothered to do so.
I attached the following pdf: ?VW_Blink_Codes.pdf

with my '93 AAF engine, I use VCDS and an OBD I to II adapter and VCDS reads the digifant computer fairly well, allowing you to see fuel injection opening times, etc.? The labels within VCDS are pretty accurate for the data fields iirc.?
Hope this helps!

Yes, this works very well. I have the same setup, and also a VAG Altel reader with the same pigtail adapter. Reads all VAG codes, transmission code (if you have an auto, thank goodness I don’t these days). Definitely some budget friendly ways you can get a lot more out of the computer than blink codes.

I use this on all my VW’s - 93 EV, 03 GTI 20th, 04 GTI, etc. Have used on a 2001 TT I used to own as well, has all you need for deep VAG codes, ABS, HVAC, etc. for cars that have that capability to report. On the 93 EV, I use the pigtail adapter, and it works amazing. You can pick these up pretty cheap on eBay.

I have a 1995 EVC and I have used RossTech VCDS with it. Most of the measuring blocks are labeled on groups 001 through 006 or so. If you hover over the data field, most will give you a range the value should be at during idle. Another useful feature is the graph function, though it takes some fiddling to get the scale correct.? Another tip is to only use one line at a time since the refresh rate is so slow.?
Hope that helps, Quinn Haughey

@Quinn - learning something new from you. I had no idea that a hover over would give the expected range/values.
I'll test that now. Just about ready to do another test drive around the block. I assume most measuring block values should be taken at normal operating temperature... not fresh off a start. Would you agree?
?
Yes, I have the OBDII to OBDI adapter... for the others that replied thank you too.
|
Yes I would say that most likely the ranges displayed when hovering over the value will be at normal operating temp. I also think it is useful to see what the values look like at cold start and as the engine heats up.?

Display Group will show actual readings...
Hovering over display shows the 'expected max and min range of the reading'...
|
Hey guys, I don't know what I'm doing wrong. I tried the mouseover, but I don't have any values showing.
Are you guys OBD1? 1993?
|
Perhaps it's your version of VCDS? I think I'm using the most recent
version but would have to check my shop computer to be sure.
My '93 has two 2-wire plugs for the OBD I connection and I have an
adapter to the OBD II style port (just 4 wires in there actually) to
connect to my HEX-V2 interface...
Hope this helps!
Cheers,
Bob

off the top of my head, those look quite reasonable to me. I don't
recall any measurement block directly showing the o2 sensor output...
If you suspect problems with the o2 sensor, you might try simply
unplugging it; forces the engine to go into a default mode (which it may
already be in if the sensor is faulty).
Hope this helps!
Cheers,
Bob

Page F 01-28 in the Bentley lists group 01 - parameter 3 as the o2 senseor
But it doesn't list a value.
My VCDS doesn't do the mouse over range of values.
Can someone else check it?
Other searches have yielded value should be 0.09-0.1 when at normal temp.
Mine if showing essentially 0.01 / basically no voltage.
?
I ordered an o2 without the connector ($26) to swap in.
Would be nice if anybody can post their value.... for group 01 - parameter 3.
|
My o2 sensor bounces between .9V and .1V constantly while running. The O2 has a narrow range of oxygen concentrations it can see. If the exhaust has a lot of oxygen (engine running lean) it reads .9 or 1V. If there is a low amount of oxygen in the exhaust (engine running rich) the sensor will read .1V or below. If yours is steady reading 0.01V, it is likely your O2 sensor is dead.?

Thank you @Quinn.??
New O2 sensor (upstream) should be here in a few days.? I'll report back results.
|
Here are some photos of the old and new O2 sensors (upstream).
?
Next, I'll be checking the voltage on it again.
I still seem to have a higher than expected idle... like 1300 it seems.? When I check the O2 voltage, I'll try to get some real idle RPM data to confirm.
I think normal RPM on a 1993 should be sub 1000, correct?
|
My 95 usually idles around 800 rpm or so, which I think is pretty standard. If you have an elevated idle, I would guess you have a vacuum leak somewhere. Check your hoses and follow the diagram. The braided hoses tend to crack over time.?
