Hey guys I will need some help with my friend's Canadian Accord. I need to know where the vtec pressure switch is on the motor. I will also be updating the thread as I get more information to what is going on with his car. Dealer quoted him $3K for repairs with no internal engine damage

 

There is no "pressure switch", but there are 1) VTC Oil Control Valve and 2) VTEC Solenoid Valve.

I think reason for high cost is chain removal is req'd.

suggest downloading an emanual from automanualsource.com for $22.

good luck

 

damn, that sucks is the chain removal required for both or just the control valve? I have never heard of this type of failure on a car with only 88K miles on it.

 

Not sure. Replacement of VTEC Solenoid Valve was not addressed in shop manual.

I did find following for VTC actuator replacement in my files.

What code/s are presented? This should isolate problem somewhat.

good luck

 

There is a VTEC oil pressure switch. Issue will depend on trouble code(s), etc.

 

My friend is in Canada and I am here state side. I am waiting for him to scan the dealer estimate so I can further help him. No way what he told me so far should =$3K Canadian (or us for that matter)


This is what I got from him so far


VTec issue
lower ball joints and tie rods

 

Further look found that VTEC solenoid valve is addressed in Fuel & Emissions. It does appear to be replaceable w/o removing timing chain.

Vtec pressure is part of the Vtec solenoid valve assy.

Code will tell what circuit is to be investigated.

good luck

 

OK I got the 2 codes


P2647 and P0122 so I know what to check first


We are going to clean the screen and see what that does and then replace the TP sensor with Honda OEM.

 

I should have the rest of the list by tonight indicating what else the dealer said for $3K

 

I think the reason they are wanting so much is Honda does not sell the TPS - you get a whole TB unit.

EDIT: but as you know, there are many tests that need to be done before just "replacing" the part the code is for.....which it sounds like the dealer didn't even do ....they read the codes and said "you need a new X".
