Stock 02' with F45 suspension 75k miles. Top bolt for the arm of the Electric Suspension Position Sensor part #22153636 has broken off leaving it lose and hanging down. (Curious why this didn't throw an error code btw).

Is this part/sensor only found on the F45 suspension? I'm already chasing down a front and rear suspension squeak and have lubed sway bar bushings already. Found some scrape marks on the bottom tube of the shocks.

Interesting the parts department at my local Chevy dealer is now showing 2 of the 4 F45 shocks as "discontinued". Wonder how they would handle the request to replace them? Would they brake down and order simulators or reprogram? I know they're $900!! but what if someone wanted to keep the option?

So.. will I still need #221153636 Electric Suspension Position Sensor if I scrap the F45? Its a $500 part, should I try fix the connecting bolt?Hurting anything with the arm floating in the wind? Would prefer to reprogram vs simulators if I scrap the F45. Will it be tough to find someone to do the reprogram?

Thanks to all Glenn in San Diego-

 

I have done a bit of research here on the forum regarding my F45 suspension and I plan to replace it this year with coilovers. I'll share some thoughts...

If still on your original F45 shocks at 75K miles, they are probably shot. I'm at 50K miles and the front end is too soft even on performance mode. Options for replacing:
1) Try to replace with new F45 shocks. Cultrag performance had them the last time I checked. This will be very expensive.
2) Replace with F55 shocks. Paul Koerner is a certified corvette master technician who does Q&A seminars at Corvettes at Carlisle. He suggested that for F45 shocks, it would be better to replace them with the newer F55 shocks. He said it is a far superior shock and similar or lower cost (I did not verify). He said the shocks hook up the same, just plug and play, but there is an extra module you need to plug into the F45 module in your rear storage compartment. So, there is an extra piece, but everything is plug-n-play; no programming and no wiring. Check with Cultrag for the extra part. Paul said his dealership did a bunch of conversions on C5s when F55 first came out.
3) replace with non ride control shocks. C6 bilsteins or aftermarket coilovers seem to be the most popular options.

#3 is the cheapest method but you need to delete the F45 option on your car to avoid codes. This can be done in a couple of ways...
1) Custom tune with a tech 2. The exact procedure can be found on the forum if you have access to a tech 2 and want to avoid going to a tuner.
2) Buy simulators ($70-80).
3) solder your own resistors into each circuit
4) Keep the original plug by removing it from the shocks. See this link below... post #155 in the C5 Tech DIY sticky...

I plan to try option #4 when I take the F45s out to get me by until I get the tune updated. If this is the piece that came off of your shock, it could explain why there are no codes.

 

You can fool the system using 10ohm 10watt resistors one at each corner. Then you can add C6Zo6 shocks or any other brand you may prefer. If you wanna take a trip up to Oregon I have a Tech2 and can tune it out

 

Real question is do I need to replace this part (Electric Suspension Position Sensor) if I'm planning on scrapping the F45? I'm I hurting anything with the arm of this sensor not connect to the frame?

 

What part broke? The Arm or the link?

 

The upper part of the link is a black plastic cup or bowl - far right in your box. A small bolt with a round head fits in the bowl so it can pivot. Other end of the bolt screws directly into a threaded hole in the upper A arm. This small bolt snapped. Ball end of the bolt still in the bowl-other have still in the A arm. The link not sold separately and the bolt itself is very unique to say the least.

 

I sent you a Pm

 

Can this sensor be taken out completely if the f45 is being deleted?

If you take all of it out you will need a Tech II to delete the F45/F55 RPO
