Throttle module S60 2001

I have had numerous problems with my 01 S60 and am wondering if others have had similar experiences. The latest occured today when it conked out on the highway (fortunately I was able to pull to the side!) and had to have it towed in. It was a faulty throttle module. I have had to have the fuel pump replaced twice in four months (is this legit or was the mechanic grasping at straws?) as well as a new starter.

Please let me know if anyone else with a 01 S60 is also having troubles...I'm ready to trade-in and am wondering if I should give Volvo my business...needless to say, after having to be towed four times since October and having the car in the shop for more days than I care to mention, I'm pretty frustrated (and angry).

I love the car (other than the break-down factor) and am looking for some advice/guidance about my next vehicle. On that same note, what are your impressions of the AWD model vs. the FWD? I would like the AWD but want to make sure it is reliable and worth the extra few bucks.

Thanks a lot!
JM

    My friend, I and an overwhelming number of other Volvo owners feel your pain. I believe you are referring to the electronic throttle control module (ETS on your dash). If that is the case, the module is defective and it has failed on countless cars from model years 1999-2001, although I think another board member said that the 40 series (?) does not have it. But I am pretty certain yours does.

    Do a search for "ETS" or "electronic throttle control" and you will be greeted by post after post of this failing and Volvo refusing to do anything about it. You could also just scroll down to my last couple of posts on 2/11 and 2/3 discussing this issue.

    I hope yours was still under warranty. For those who are not so lucky it is a $900 - $1100 repair that can only be done at the dealer b/c of the need to download upgraded software.

    I am urging anyone who has experienced this problem to contact Volvo of North America and complain 800-458-1552.

    As you experienced this is a dangerous defect - you conked out on the highway (what if you couldn't pull over), others have had engine/acceleration surges, or sudden loss of acceleration. For a company that continuously touts safety and reliability as its main priorities, this is totally unacceptable.

      Thanks for the insights, Dave. I read all the ETC-related posts and am more angry (p'ed-off, actually). What a crappy way of doing business--letting people break down and then fixing it (and collecting $$) versus recalling the cars and fixing the problem. Reminds me of Ford's cost-benefit analysis of installing the fire-retardant plate between the gas tank and bumper of the Pinto. And that was only an $11 part!

      Unfortunately, the car has 52K miles...I'm out the big bucks like many others. The real rub is that I brought the car in with 48K after it failed to acclerate at highway speed. I was told that it was a fuel-pump problem, though I had a new fuel pump installed three months earlier. Ya can't tell me that the dealership wasn't licking their chops at getting $1K once the ETC failed!

      According to other posts this problem has been fixed in new models...or has it? Should I hold on to my present car or will other parts fail? Is there any other chronic problem I should be aware of before I am stranded again?

      Thanks a lot!
      JM

        JM -
        My understanding is that they developed a new throttle control system in the new models b/c of the defective nature of ours. Also the one's that they replace the defective units with is supposedly OK. I haven't heard of the modules failing again after replacement.

        As far as holding onto your car. Tough call. I think I'm going to bail out of mine - it just hasn't inspired any confidence in me. I personally think that Volvo's reliability is relic of the past. The newer models just seem to have numerous problems - none of them cheap.

        Everytime I log on I see someone else posting about their ETS. Unbelievable. Again, I think anyone and everyone who has or had the problem should call and complain.

        On the brighter side (for others, but not for those that have spent their $$ already) 'mastertech' seems to have been able to repair it. And since he is repairing the original module, you don't need the upgraded software. I know that a lot of folks have sent their ABS modules to him and been very pleased.

        I also saw your last post on this thread. You have a very valid point.

        -Dave

        I'm curious, having read the post regarding faulty UTCs. I have a 2001 C70 which has begun having starting problems during this past year. Not quite the same problem you guys have been talking about but I wonder if it might be the same or related.
        What has been happenning is the car generally starts fine but on occasion it will turn over but just won't fire. It's been back to the Volvo dealership many times and they can't figure out the problem. It has only failed to start once for them so they do believe it happens and I''m not crazy. Trouble is, no codes turn up so the computer can't tell them anything. (Gee, what did mechanics do be for computers?)They have thought that maybe the chip in the key is bad and suggested using the spare which I did but the problem continued.
        I have felt it is a fuel pressure problem and have suggested they change the fuel pump but they haven't wanted to do that unless I pay for it so naturally it hasn't been done yet. The reason I feel it has somethng to do with the fuel pressure is because when the car doesn't start I turn the key on but don't crank the engine for a few seconds, thinking that I am allowing the pump to build up pressure, and then crank it and it starts fine.
        Any thoughts or anyone else experiencing the same problem.
        George

          History of ETS failure? S60 2001

          After reading more past posts (and George's post above) I did some contemplation into my car's problems. Turning the clock back, here is a run-down of my problems:
          *Summer 2002--cruise control failed three times. Dealer claimed that the computer codes didn't match up, so they installed the "wrong" codes to get the car to run.
          *October 2003--car wouldn't start--new fuel pump, starter, reset the key chip--bottom line: they couldn't seem to diagnose the problem
          *January 2004--car RPMs increase but no accleration--replaced fuel pump (I thought this was odd since I got a new fuel pump in October)
          *January 2004--at highway speed the car stalled--thought I had frozen water in the the fuel system (it was -10 degrees) and added Heet and the car started and thought nothing further
          *February 2004--car stalls out again at highway speed. Again thankful for guardian angels to guide me to shoulder. Started on second try. Ten miles later, same thing occured, but car woudn't start. Towed in and the dealer diagnosed faulty throttle module. Of course they had the part in stock and was fixed within the day. To add insult to injury the dealer's hard drive "fried" (his words, not mine) and couldn't download software. So, here I sit without a car.

          Are all of these problems (cruise control, not starting, increasing RPMs, stalling out at highway speed (three times!)) all affiliated with the ETS? I'm no car-genius, but all seems a bit fishy. Do I have a case here of repeated mis-diagnoses? Do dealers know about this problem and don't fix it, thus putting lives in peril (with stalls at highway speed)?

          Note: there is no ETS indicator light on my 01 S60, so I had absolutely no warning of the problems to come.

          Thanks for reading all my rants and for your advice!
          JM

            Is this car a turbo?

            Would you happen to know what any of the codes that have been read on your car?

              No, it isn't a turbo...it is the base model 2.4L engine. No, I do not know the codes....

                Well the good news is that not that many throttle bodys on the Non-turbo have been replaced. There is a thick rubber hose that goes from the air cleaner to the input to the throttle body held on with two clamps that have 7mm screws on them, loosen both clamps and manover the hose out of the way far enough to get in there and clean the throttle plate and walls with a rag that has carb cleaner on it, don't spray directly into the throttle body. That will solve your surging problem.
