2004 S80 2.5T AWD Throttle Body Failure

Thanks for the input, but there has to be something else I can try that doesn't require splicing wires...

In the mean time, I think I'll clean the connector as best as I can, reconnect it, and then hold it in place with... a god damn cable tie.

I'll also be looking around for '04 S80's at the junk yard and hopefully find myself another connector.

Jimmy mentioned in his post above that Volvo sells connector cables as a separate part. He would know first hand

Thanks Mike, forgot Jimmy mentioned that.
I called my local Volvo dealership and tried to explain to them that I need a new connector cable, but they didn't know what I was talking about and kept asking me if my throttle body needed replacing.

I ended up emailing them the same pictures that I posted here in hopes that they can figure out that I'm looking for a connector and not a throttle body.

I've also tried looking on Tasca and other online parts stores, but with no luck. That junkyard option is becoming more and more likely.

It may pay to PM jimmy to see if he can look it up for you. So far jimmy's been spot-on with his advice and has saved my bacon many times.

Quick update in case anyone wanted to know.

I'm still searching for a new connector. The Volvo dealerships in my area do not sell the connector terminals for the throttle body seperately. If I wanted a new connector from Volvo, I would either have to buy a new throttle body, or the entire engine wiring harness. So it looks like I'll be visiting a junkyard pretty soon.

In the mean time, I have cleaned the connector and tightened the connection with a plastic cable tie. The car is running with no problems. So at least I know it's just a loose connection that caused the problems and I don't need a new throttle body.

Thanks for all your responses, saved me quite a lot of money!

I have finally replaced my old connector. It was surprisingly difficult to find, but luckily the guy who had it also installed it for me.

Bad news is, the problem still persists. The car drove fine for 2 hours and then all of a sudden, once I got closer to home (of course) I got the "Reduced Engine Performance" message and got stuck in limp mode.

I'm pretty frustrated. I was almost certain it was because of the plug, but now I find that it clearly wasn't. I think I'm going to have to buy a new throttle body

Again let's look at connectivity before failure of items. Surface corrosion on the ECM plug pins can have the same effect. Before replacing the throttle (again) have the ECM contacts thoroughly cleaned with contact cleaner. You can purchase the ECU removal tool for around $30 from IPD and some contact cleaning spray for about $8.

I once replaced a Bosch throttle on a 2003 XC70 as well as new MAF to no avail. Once I cleaned the contacts of rhe engine computer the throttle codes disappeared & I also got rid of a pesky ECM-003 faulty communication code that had been on the car since first diagnosis.

I've replaced at least 120 Magnetti throttles since then but never a Bosch one. Recently a diesel 2008 XC90 Bosch throttle failed but that's a different part number to the petrol version.

Thanks Mike, I'll definitely take a look at my ECM and give it good cleaning. I'll let you know if it solves the problem.

Unfortauntely IPD has no ECM removal tools in stock which is just my luck...
I found one on Amazon, which was actually cheaper, but they don't ship to Canada.

Any ideas on where else I can look to get one of these tools?
Or even better, is there a way to take out the ECM without the tool? I'm probably only going to use it once lol.

Look up the part number on IPD's website and try Tasca Parts which are an OEM supplier. Otherwise try ARD Tuning.

There are 2 independantly driven pink sliders on either side of each ECU. They can be slid to the upper most position for ECU removal however they are difficult to access.

Hi,
I am having the exact same problem. I have the Bosch ETM on my 04 S80 but I took it off and cleaned it along with the connector- It didn't help.
Did taking the ECM out and cleaning it help? If so I'll buy the tool and remove both modules and spray electrical contact cleaner to see if it helps me. I just dont know what it could be.
