    3200 throttle issue driving me nuts

    If you can point me to a reasonably priced 'virgin' TB, please let me know :frustrating:

    3200 throttle issue driving me nuts

    I am in negotiation with the seller of the 'new' TB I purchased. He also still has the engine ECU as well as Code ECU. If I can replace those, along with the transponder in the key, the car should work again. Let's see if I can get a good deal from him.....

    Thanks, I also found an interesting document regarding Volvo ETMs: http://www.volvoklubs.lv/e107_files/public/1357832393_1588_FT31575_drosele.pdf They look very, very, very similar to ours ;-)) Will start searching for an electronics company now Keep you posted

    3200 throttle issue driving me nuts

    Also measured at the supply pins (highlighted in the picture), and there is a minimal voltage of 0.17 Volts very briefly, so barely anything. I also suspect the transistors or power parts, but have too limited knowledge to tell what is what .... And the connectors are so tiny, I am afraid to...

    Nope, the butterfly motor is just a regular motor with two connections (they are behind the small oblong shaped cap) Off course it moves freely. Also checked with separate powersupply, no problems there. It is really in the power supply from the ECU --> Motor

    3200 throttle issue driving me nuts

    OK guys, I made a little progress this evening. I compared the TB I bought with the one in the car, and indeed they are different. The shape and connectors are exactly the same, but for instance the partno's on the right Marelli caps are different (see pics). This leads me to believe that the...

    3200 throttle issue driving me nuts

    Wiring and pedal pot is double-checked, voltages measure OK too. Cannot be 100% sure the 'new' TB is OK, but was converted to contactless and said to be coming from good running car. Only difference I can tell between the old and new TB is, the year/month stamp. My existing one was dated 00/01...

    3200 throttle issue driving me nuts

    Well guys, the saga continues.... Today I bit the bullet and bought a new Throttlebody. It came from a 99 3200 GT, and had the Contact-less modification. Bolted it on this evening and turned on ignition. Fortunately the TB clicked and made a nice humming sound. Continued to start the car and...

    3200 throttle issue driving me nuts

    OK guys, I think i am a little closer to finding the culprit... Measured the voltage of both the pedal pots, and they were both 400 mV, so well within spec. Then I checked again, if the car would work after warming up a few minutes, and after 10 minutes all was good again. What I noticed...

    3200 throttle issue driving me nuts

    Haha, I was only joking ;-) I have two german cars as well, and they also have their quirks and niggles. With regard to the limp-home/throttle issue, it still exists..... Fired it up this morning and voila CEL and barely any throttle response. Very strange, drove the car whole day yesterday...

    3200 throttle issue driving me nuts

    Thanks Davy, Will check the pedal voltages this weekend (after the car has sat for a few hours). Took the car with me to work today, and drove it approx 80 miles, without a single problem. So maybe the car will fix itself, after all the car is equipped with S.H.I.T (Self Healing Italian...

    3200 throttle issue driving me nuts

    Hi Contigo, The voltage I am referring to is the voltage of the Sacer sensor at the throttle body. It has 3 pins: ground, 5v+ and sensor voltage. Have not measured the pedal pot yet, but will certainly do so shortly. Cheers rex

    3200 throttle issue driving me nuts

    Hi Guys, Hope you can help with the following: My 3200 GT (1999) starts in limp-home mode with CEL on, everytime after sitting for a few hours. Diagnosis with Unidiag throws a "P0221 - Throttle/Petal Position Sensor/Switch 'B' Circuit Range/Performance Problem" All the obvious resets...
