Hey all,

Does anyone know if there are any differences between the K20A3 power steering pump and the K20A2 power steering pump? The Honda part numbers are slightly different, but it seems aftermarket power steering part numbers don't differ between the two engines.

I have searched on Google and on the forum with no information on this, so any help would be appreciated.

Thanks!

The k20a3 pump puts out 1.050psi and the k20a2 puts out 1,140 psi, a difference of 90 psi. The pressure is monitored by the ecm through the power steering pressure switch. If the ecm senses the pressure is not correct, it can cause idle issues and hard steering.

Thanks for the info! Where did you get the info from? I searched everywhere and I could not find anything.
