Hi Guys,

Check Engine Light came on today with the "flashing arrow" in the dash
The tranny working fine otherwise !?!? (never got into limp home mode)
and I checked for codes

223 in A1 --> Throttle position (TPS) sensor signal too low
243 in A2 --> Throttle position (TPS) signal exceeded voltage limits

I cleared the codes but the idling RPM is around 1500 in instead of 900

Any technical info on that throttle position sensor? where is located exactly ?

Thx

Hi Ken,

The TPS is on the throttle body, I believe on the inboard side, closest to the engine. You should be able to get a replacement from www.fcpgroton.com for $40 or so, assuming you are comfortable handling the repair yourself. Otherwise, you may expect to pay $200 for this at the dealer or a little less through an independent Volvo mechanic.

The TPS feeds a signal to the tranny control module (TCM), to help the tranny determine when to shift, so that is where the arrow is probably coming from.

OK dookie! that makes perfect sense since the CEL & flashing arrow came back this afternoon with the same fault codes and tranny is still shifting fine.
I'll order that TPS 1st thing tomorrow morning.

Thx a lot for the explanation V70BB .

We've replaced one TP sensor, ever. I don't know what the weather is like in your neck of the woods, but it just got "freakin" cold here in North FLORIDA. When the weather gets very cold, and strange things start happening on your car, think back to science class...cold = contraction; hot = expansion. I'd probably check the connector on the TP sensor, and the body grounds for said TP sensor before replacing it. Cleaning and electromotive greasing a connector and cleaning and tightening grounds often times fixes a problem.

Just my two cents,

Chris

Hi Chris,
It has been g*d@mn cold here latelly (-4F). I cleared the fault code again and it didn't came back yet but it's warmer now... I'll wait n see.
