Ok so i ripped my LS apart to do what I thought was an off timing belt (code 13)... got it all apart, belt looked okay, and was seemingly in time. both CMP sensors checked out... went to put it all back together and noticed this sensor had no plug/connector to be found... after searching, its something to do with the cold start injector timer(?) but i couldnt find where the connector should be... can anyone help me locate it? Ive never touched one of these 1UZ's before. thanks!

also, i have two out of three vacuum lines blocked off on the throttle body.. any idea what they went to? nothing looks out of place.. at first i thought they were for the EGR valve? this car is really starting to worry me...

 

are we looking at the circle or the arrow?

 

Plugged hoses from the throttle body may have gone to the ACV valve on the PS pump; leaking ACV valves are often bypassed with no impact. I have seen some posts here about the connector for hoses (circle), but I think they too are often disconnected without creating problems, but I don't remember what the connector does.

 

Code 13 is related to RPM signal. Check the CKP sensor for open/short circuit. Or A defective CKP sensor.

As for the Vacuum lines that goes to the TVV, look at the engine sitcker. Should have a vacuum line diagram.

I believe that connector is for the ECT sensor?

 

The PS pump ACV vacuum lines actually run from the air intake hose and the front of the intake plenum. i know, i blocked them off

after some research it appears my car doesnt have an EGR valve and thats what the connections on the TB are for.

as to the missing electrical connector, i know what the thing is. What I dont know, is where on the engine harness the connector comes from. lol. either way, its back to running okay now, but still gives me code 13. all of my sensor test fine. so i dont fricken know. also, the TBelt isnt off (code 13), i just put it back on. 5 times. >.<

 

Did you even read my post??

Your car is a 94, it should have an EGR.

 

What it should have and what it actually has (or doesn't have) are two different things.

Yes I read your post. The missing connector isn't for the ECT. Its for the cold injector start timer... im trying to figure out WHERE the connector went. Lol. Not what it is.

I pulled out both cam sensors and the crank sensor. Both tested within resistance.

 

Look on your car emission label see if it says Egr on it.
