Last week I started a thread about no power well it is actually a vss problem. Basically you stomp on the gas and the TC don't lockup plus I get a code 24. Now my problem is I have the double pointer speedometer I know I should have the 145 mph speedo. How can I fix this problem what do I have to do. I am basically asking where do I need to start I really want to fix this problem.

 

Hey, warren,

Listing your car's year, make, model, engine and so on is very helpful.

Apparently an early model dual-pointer speedo was swapped into your car at some point. If in that swap, the VSS wasn't hooked up (backside of the cluster 82-89) for some reason your problems might be explained.

Its sa 1989 irocz. The car ran fine before I let it sit for a month aftefr that I changed the maf sensor. My question is will any vss work or do I need a 145 mph cluster fo an 1989 iroc

 

I've swapped my speedo head several times (though never an 82-84 dual-pointer model) from an 85 to 110 to a 140 and never experienced any issues.

My main concern was if they were the same and if it would work with my ecm. I have never messed with the vss on any type of vehicle. Basically I want to know can I go to napa buy a vss for a 1989 camaro and have it work without problems.

 

Since speedo heads and entire clusters (V6 to V6 and V8 to V8) are frequently swapped between auto and manual cars without serious issues, I'd guess vehicle speed sensors are the same. I'd also guess that the difference could well be the ECM and how it appropriates the signals it receives.
