04 Volvo S60 Fuel Tank Pressure Sensor/ Failing coils

Megatrav · Post by **Megatrav** » 23 Mar 2019, 11:57

Hi, just joined the forum!
I am having some issues with my 2004 Volvo s60 2.5t;
I recently got the codes read at autozone and it said I have a all 5 coils failing and my Fuel Tank Pressure Sensor is also failing.

I have no been able to find the Fuel Tank Pressure Sensor, only the Furl Rail Pressure sensor which I have changed within the past year (also failed out).
Any ideas what this is or where to get a replacement.
I have seen some used ones on eBay, but I was hoping to get a new one if possible. I have not contacted the dealer yet, as I wanted to come here first.

As for the Ignition Coils, within the past 8 months, I replaced all 5 with very inexpensive ones. It drove fine for a while and now it is saying all 5 are failing again.
Is it a bad idea to get no-name ignition coils?
If so, which ones should I get?
Are the NKG ones okay?

I am also going to be swapping the spark plugs soon- I have always used Iridium plugs, but wasn't sure if I should stick to those or use Double Platinum, Ruthenium, etc.

Thanks for any information or help!

Hello and welcome to this forum!

There is no fuel tank sensor, but there are two parts that can fail (google up) PEM and FPS. Get used PEM from Ebay if needed (look for one without corrosion).

Yes, cheap coils is not a good choice, may replace them with used genuine one from junkyard or Ebay (hint: www.youtube.com/watch?v=uHLgXQo6E9c

We buy parts from sites like Ipdusa and Fcpeuro, usually look for these brands: Bosch, Sachs, Lemforder, Ina, Continental

Spark plugs are specific for your engine, see sites above

Thank you very much for the reply. I'll look at swapping the coils for a name brand version and see where that gets me.
If I am still getting errors, I will look at the other part you recommended.
Thank you

Wanted to leave an update-
I swapped the plugs and coils. The plugs had oil on them. Looks like I have a bigger issue.

I would assume there is a leak. I've read that my car doesn't actually have a head gasket, so I have no idea what to do.

Car is running better after the swap. Not perfect, but I haven't reset the check engine light yet. Regardless, the leak is probably going to cause the coils to start failing again.

Another update- turns out there's no leak on the plugs.
My car is burning some oil, but no big deal.

I reset the codes and I am getting MAF sensor failure.
I am ordering a Bosch next week to replace.

Like a dummy, I spent $25 on a cheap one and its failing again.

Hopefully this finally fixes my issues.
