2004 SP 122 location !!
If anyone has the FSM for an ‘04 I need a little help...helped a friend this afternoon with a P0135 (O2 heater circuit) DTC...Loaded the ground with my trusty headlight bulb and NOTHING !!...when we went to check SP122 it wasn’t there...couldn’t find it anywhere...WTH !!...if anyone has the FSM can you tell me if SP122 is at the “engine harness 1 foot from breakout for starter solenoid, under rear left corner of battery tray”...we also had an open in the O2 heater itself so we had 2 issues...bad O2 and a bad ground...a new O2 fixed half of the problem but need to get the ground fixed !!...thanks !!

I think it is on the engine block,right side.Had an issue with mine and I am pretty sure that is where I found it.Looks like a connector but it is actually a ground slice pack.Have to get under the car to see it.
