This many error codes? With Log

[jeff24680]

Is it possible to have this many error codes and the car run completely fine with no knock(even though im getting an error for this sensor as well) great AFR's, and seemingly no problems. I am getting these as reported by EvoScan 2.6


Throttle position sensor
ISC motor position sensor
Engine coolant temperature sensor
Crankshaft position sensor
Camshaft position sensor
Vehicle speed sensor
Knock sensor
Injector circuit
Fuel pump relay
EGR sensor
Ignition coil
Ignition circuit

My only issue right now is after warm up/driving when ever if I am in neutral my afr will almost always hover around 16(15.6-16.5) sounds Lean to me, but according to this log all my idle controls seem to be functioning normal and I am idling at a perfect 750-780, WOT is a perfect 10.8-11.4, and cruise AFR is a perfect hover of 14.5-15.3. The log hear shows idle right before 2 mild throttle presses and return to idle. MOD List is UP TO DATE

Do i need to replace all these sensors? Like WTF

 

[EclipticalGS]

ecu is bad?

 

[jeff24680]

That's not very helpful

 

[toddevo]

what ecu do you have ?

 

[jeff24680]

As far as I know, the ECU has never been changed so it would be a 99 ecu, I know it is at least a 97+ because it works in evoscan a reports with MUTII with very good speed.

Might I add all the work in my profile was done in one complete 30 day session.

I.E.

-Engine and Trans pulled,

-Did engine work while waiting for arrival of trans

Attached trans back to engine and dropped it back in, removed emissions and plugged everything back in, broke the smaller coolant temp sensor and replaced it with one that a local guy had, I have unplugged and plugged all sensors back in. Reset the ECU twice, I am just so confused as to why so many sensor are giving me warnings but yet the car is running almost 100% perfect minus the idle AFR that I also can't figure out, so was just wondering if the two were related

 

[hhuricane]

Check the alternator output. If the volts are low the computer will start throwing a bunch of bogus codes. It gets "stupid" at low voltages.

 

[jeff24680]

Thank you I will check that when I get home, I don't know why I didn't think of that, errrr.

 

[jeff24680]

So I tested the alternator through EvoScan and it is constantly above 13V, at idle when I turn lights and ac on its drops slightly below 13 then recovers, I just replaced the negative post on the battery and made sure everything is fastened down securely, I bought another 4 ga ground wire and I want to place it somewhere, currently I have

1-battery to firewall
1-negative post of battery to starter
1-IM to firewall

These are the ones I am positive of I heard there is another that is supposed to go from tranny to chassis but I am not sure if it is plugged in. Where do you think I should put this other ground wire? I was thinking somewhere near the front o2 sensor to the cross member or front frame.

Does anyone else have any ideas as to why so many errors would come up yet the car runs at 95% right now?

 

[PieEyedPiper]

If you clear them do they all just come right back after a drive?

 

[jeff24680]

Yup, I just cleared them before work this morning and they came back by the time I got home, wierd sometimes they all appear and sometimes they dont, MOSt of the time they do.

Any ideas?


**UPDATE**
Here is a picture of my terminals right now just for soem reference

 

[reddragonvr4]

pie that was what i was going to ask. if they do come back start with the frist error and try to fix it. and just go down the list. check wires double check everything.

there has to be a falt in the wires some were. inless you evo scan is falty? can you get another ecu and put that in and see if that fixes the problems.

 

[jeff24680]

98-99 Ecu's are hard to come by if anyone has oen for sale let me know , and I guess I can do that its going to be a bi***, but we'll see. I guess I can start by checkign the wiring however I have unplugged and plugged all connectors back in already.

i figered they wouuld be hard to come by, i didnt know if there was anyone in your area that had one. do you have a voltmeter if so you can do a continuity test.

 

[jeff24680]

Yes I do have voltmeter, how would I go about doing this continuity test?

How to Test for Continuity | eHow.com

this should help ive used it on mine when i needed it

 

[jeff24680]

I figured out what my problem was.


When using evoscan there are multiple protocols to retrieve CEL codes

Simply put, I had MUTII EFI selected when I should have had OBDII EFI selected did this and now all CELs except my boost control solenoid and EVAP are gone and thats becasue those two are not plugged in.

Thanks!

 

[reddragonvr4]

cool glad you got it fixed!!
