mike300z Posted October 14, 2013 Share Posted October 14, 2013 (edited) My car is throwing code 55 EGR temperature sensor or circuit. I have checked and my egr is not stuck, and seems to be actuating under vacuum. I cleared the code and it came back. Searched and someone else said they replaced their ecu and that fixed the problem. Not sure about that, but that does not seem like a solution for me. Also this car was purchased new from Tennessee.

86 Wonder Wedge Posted October 15, 2013 Share Posted October 15, 2013 I'd drop the ECU and see if you can see any salvage yard marks on it.. may have been replaced with a Cali ECU. Or could have been a Cali emissions-spec anyway.. Is there a sensor in or near the EGR valve? Would sort of look like a mini O2 sensor.

NorthWet Posted October 15, 2013 Share Posted October 15, 2013 The EGR code is caused by a problem in circuit/wiring of the EGR's vacuum solenoid. This is a common problem, and the usual cause is a bad solenoid. This solenoid is a little plastic box with 2 vacuum lines attached, and a pair of wires running to it. The solenoid coil tends to fail. Replace with another solenoid, or you can also replace the solenoid with a resistor of a specific resistance Quote Link to comment Share on other sites More sharing options...
mike300z Posted October 16, 2013 Author Share Posted October 16, 2013 anyone have a solenoid for sale? Quote Link to comment Share on other sites More sharing options...
ivans imports Posted October 16, 2013 Share Posted October 16, 2013 Use a outback one 90 % more reliabble and easy to find will have to modify wire harness but a good fix Quote Link to comment Share on other sites More sharing options...
mike300z Posted October 16, 2013 Author Share Posted October 16, 2013 can you tell me more about this swap? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted October 16, 2013 Share Posted October 16, 2013 Guys....it's the EGR temp circuit code, not the solenoid code. The EGR temp circuit code would only be on cali spec models. You need to check the manifold and see if there is a sensor there right at the base of the EGR. If not, then that will explain the code. Either manifold swapped into a Cali car, or more likely a Cali ECU swapped into the Tennessee car. Just to be clear, it's actually lighting the CEL solid with a real code? You aren't interpruting the model code flash of steady 5-5-5-5........which IIRC would be a manual, 49 state SPFI car. 1 Quote Link to comment Share on other sites More sharing options...
mike300z Posted October 16, 2013 Author Share Posted October 16, 2013 I think you may be right it does seem like a 5-5-5-5 so its not throwing a code? Quote Link to comment Share on other sites More sharing options...
El Presidente Posted October 16, 2013 Share Posted October 16, 2013 (edited) Yeah, 34 or 35 is a EGR soleniod/valve(cant remember exactly) on 49 state cars for your year, continuous 5's is a designation code, so nothings wrong. Is your CEL light on? Josh Edited October 16, 2013 by El Presidente Quote Link to comment Share on other sites More sharing options...

86 Wonder Wedge Posted October 16, 2013 Share Posted October 16, 2013 Yeah. I code 55 is 5 long pulses with 5 quick ones in succession. 5 quick pulses, continuously is "5" meaning Federal emmission, MT. No troubles. Quote Link to comment Share on other sites More sharing options...
mike300z Posted October 17, 2013 Author Share Posted October 17, 2013 cool now I need to find out if this exhaust leak is causing major loss of low rpm power! Quote Link to comment Share on other sites More sharing options...
