15-engine coolent temp
23-intAke air temp sensor
32-egr system failure
43-knock sensor
44-oxygen sensor error
54-digital egr valve selenoid 2 error
Or 54 could be fuel pump circuit(low voltage


These are all the codes i got on my 88 camaro rs 5.0 tbi 5 speed stick



I know the sensor pigtail has to be replaced
Egr might be beause i habent hooked up the t with the air pump and i connected it directly to the tbi
Knock sensor is missing that i know
Oxygen sensor says its lean? Wtf
54 might be same as 32

 

Until you fix the obvious faults , little point looking at the codes because a fault say with the CTS can give problems with other things
The sensors were installed by GM for a reason ; to make the engine run PROPERLY !

 

Well tomarrow ill try to rewire the egr and some connectors

 

also its not like i took the sensors off... it was the Previous owner

 

Forget the EGR
Engine will run happy with no EGR ;it only throws a code.

CTS is the most important sensor for engine operation then O2 then knock sensor
If the other sensors( or wiring ) are faulty then you will have problems

 

CTS= Coolent Tempeture Sensor?
the fan doesnt come on unless i turn on the AC and i always run it with the Ac/FAN on.... might that be an issue?

 

soo after a new battery i only had code 15... fixed code 15... CEL wont come up untill operating temp... now i get 32 43 44.... i replaced knoking but the pig tail was borken so im going to replace it... also o2 sensor will be replaced.. and 32... guess i need a new EGR

 

So a new battery made all our codes but 15 dissapear? Doesnt make sense to me..

If the pigtail is broken that would explain the code for the knock sensor

Check the diaphram on the egr first, while its running make sure you feel the diaphram moving

 

how do i do that

 

lol. just put your hand under the egr while the cars running and try to tell if you feel the diaphram moving. Also, while its off, push on it a little bit. It should be very easy to move, if it gives resistance it probably needs to be replaced

It could also be your egr temp sensor, to be sure i looked it up and it says code 32 is Fault in exhaust gas recirculation valve diagnostic switch, hence the DIAGNOSTIC SWITCH. Your EGR may be ok, its possible the temperature sensor for it is the problem.

Either way, check the EGR diaphram first then go from there

 

well i ordered the ALDL cable... should get home around Wednesday.. i had code 15... fixed that by replacing pig tail and CTS... not i get 32 43 44... but i only get it when i go over 50 mph... while cruising code doesnt show up... also when i turn off the car the code disappears

i already got a new knoking sensor... unless i put it in the wrong hole... or the connector was broken
