Fairtax4me Posted July 2, 2015 Share Posted July 2, 2015 Was any work done recently that might have knocked some wires around? Have your driving habits changed? Driving more highway miles that usually lately? If you reset the code does it come back right away? Quote Link to comment Share on other sites More sharing options...
NorthCoast Posted July 2, 2015 Share Posted July 2, 2015 Other than installing a new Frankenmotor? No highway miles...it's a wheeler. The car rarely gets driven. Code comes back right away. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted July 2, 2015 Share Posted July 2, 2015 how long has this engine been in the car? and what engine was in the car before this? when did the code first appear, whit which engine? ps: all ej25 dohc engines 96 - 99 have EGR.

Fairtax4me Posted July 2, 2015 Share Posted July 2, 2015 Is the wire harness on the new motor the same that was in the car? And that harness doesn't have any extra plugs or wires cut out of it? Quote Link to comment Share on other sites More sharing options...
NorthCoast Posted July 2, 2015 Share Posted July 2, 2015 (edited) The only thing that changed was the block and head gaskets. No extra plugs or wires cut. Edited July 2, 2015 by NorthCoast Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted July 2, 2015 Share Posted July 2, 2015 (edited) so the car had an ej22 engine and ran with no codes. you replaced the block and head gaskets and now you have an EGR code. so the intake does not have EGR on it, you did not have to disconnect the EGR pipe from the head when you pulled the intake. i would really like to know (and GG would too,) how there was no EGR code before you replaced the block. but whatever. check the vac lines going the the passenger strut tower. there are a couple of small devices over there and those vac lines are easy to miss on the intake end. and they will throw a code, EGR i think, but not sure. any way maybe that is the problem, not the lack of EGR on the driver side. or something else like that .

NorthCoast Posted July 2, 2015 Share Posted July 2, 2015 EJ22 had the code right before I did the swap along with both o2 sensor codes. I replaced both O2 sensors... perhaps it just needs to run a full cycle. I double check the vac lines to see if one popped off. Quote Link to comment Share on other sites More sharing options...
NorthCoast Posted July 20, 2015 Share Posted July 20, 2015 Switched to an EGR harness and tied the EGR solenoid vac lines in. No more CEL. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted July 20, 2015 Share Posted July 20, 2015 I would have to guess that the original engine had EGR, someone replaced the engine with a non EGR, and the person who did the swap wired in a resistor to keep the ECU happy, then hid it in the wire loom somewhere, and the resistor finally went bad. A 97 EJ22 paired with an automatic would likely have had EGR. Quote Link to comment Share on other sites More sharing options...
NorthCoast Posted July 21, 2015 Share Posted July 21, 2015 I don't know where this resistor myth is coming from but I was the one who replaced the engine and never wired in a resistor. Just adding an EGR harness with the solenoid was all it took. Nothing more. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted July 21, 2015 Share Posted July 21, 2015 You replaced the original engine? Quote Link to comment Share on other sites More sharing options...
NorthCoast Posted July 21, 2015 Share Posted July 21, 2015 Yes. The car had no engine when it came to me so I put one in. Original engine was pulled and rebuilt by the PO and now powers a Toyota truck. Quote Link to comment Share on other sites More sharing options...
