i got a code for on my sisters 95 gle, 0407, CPS (REF), initially it would take a while to start up, now it scompletely dead. i've done a search and read conflicting information on whether the code actually means that he sensor is dead. i asked the auto parts store to order a new sensor. would the CPS (REF) cause this?

 

I have the same thing and I'm wondering the same thing. Mine used to be hard to start but won't start at all today. I haven't seen the CPS code in a week or two (I reset the ECU after checking what the code is) but it's been hard to start regardless and now I can't get it to start at all.

I'll probably by one from Autozone (it's like 75 or so) and see if it atleast helps. But as was asked above, will the CPS cause the car to start (even though I no longer get the code)?

 

what was your code 0407? cant be a coincidence, my sister siad its been starting hard for a week, luckily its sitting in the driveway instead of somewhere else, i just cleaned it and plugged it back in, and still a no go, but just the fact that both of ours dont start after a week of the code must mean it is the Crankshaft position sensor, order yours ahead of time, i ordered mine today for 69$ at autozone, straussed wanted $129. when you say wont start, do you mean no crank? because thats what im getting, nothing at all.

 

Mine turns over. It finally started after about an hours worth of trying on and off. I let it run for a bit and no code. I turned it off and then it cranked right up again. This is how it normally behaves, only it will start after about 5-10 seconds of trying and not a whole hour!

 

bump.........

 

coming to th conclusion its the starter causing the problems, anyone have any input, 0407 isnt supposed to cause no cranking, i get no cranking or clicking, possibly failure of the solenoid.

 

i'll let you know, right now im looking for the cause of the problem, started with hard starting, then no cranking no clicking either. code for 0407, leaning towards starter, hope its a quick fix, i hate wasting my day off on somethign like this.

 

bump...but yes the crankshaft sensor throws off your starting system. The camshaft sensor will do it as well

 

update:


i swapped both sensors from the car thats not starting into my 5speed, my 5speed starts up just fine, i replaced the camshaft position sensor and the crankshaft position sensor (REF), apparentyly i burned th starter too, so i got a rebuilt one from the rebuilding shop, it cranks now, but doenst start. i previously had a code for 0407, im wondering how to check the harness, im running out of ideas, what bout the crankshaft position sensor (POS)????

 

Are you sure you changed the right one?

REF is located on the lower crank pully.
POS is located on the transmission bell housing, under the car and looks at the flywheel.

 

i changed the correct one, i changed the one next to the oil pan, also swapped the camshaft poisitoin sensor as well with my 5speed. both work in the 5speed, how do i do a continuity test, i stuck in the multimeter into the harness for the REF sensor, i got no reading, i had someone crank for a split second to see if i get a voltage, i got nothing, any ideas? how do i do a continuitnity test to figure out where the problem is?

 

another thing is, it started previously, took a while to crank and it started up, and nothing was wrong after it started up, now it was completely dead, and tested the starter and the starter had died, so i swapped out the starter, and now it cranks fine (before it made all sorts of noise before it fired up) but it doenst start, just keeps cranking.

 

bumpage....

 

bumpage once again...i need some answers before i start again this morning, othwerise its going to a shop

 

I had the same symptoms not too long ago. Initially, it would have difficutly starting, taking a few cranks until finally it just wouldn't start, just kept on cranking and cranking. Went through pretty much everything you did and I just said f' it and took it to the shop.

They asked me if I had done any clutchwork recently which, amazingly enough, I did just get my clutch replaced, which is when the starting issues began. They checked the CPS and said it wasn't getting a good ground. 10 hours later, my car is put back together and starts up fine, no parts needed.

 

update:

cleaned off POS sensor, no luck, now its throwing a code for camshaft position sensor and crankshaft position sensor (REF)

 

update:

STARTED UP! i hadnt plugged in the camshaft position sensor all the way after i cleaned the crankshaft (POS), thanks those of you who helped, let this be a lesson to everyone, clean it, it was covered with filings.

im going to put in the words 0407, 0802 47, 407, POS, REF as keywords in this message to make it easier for other people to find if they search for this. The moral of this story is that the DTC aren't as accurate as one may think, 0407 had meant 0802, 0407 is triggered by a hard start as suggested in other posts from over 2 years ago.

 

Grats man! Nice job!

 

My car was doing the same thing until i replaced the starter. I wonder if the crankposition sensor still needs to be cleaned or replaced ill check it some time.

 

if those sensors are not plugged in your car will not start (my does not) so either its unplugged or its bad. my sensor has been completely crushed several times from my s/c bracket, its not really a clip anymore. just two wire and the plastic mounting piece

 

mine did the same thing when the crank sensor when bad. the one under the crank is not as important as the one by the trans. it also will throw the cam sensor when it starts to go.

 

I wish I had seen this post earlier.
one month ago, my car wouldn't start suddently and I had it towed to
the garage. Those mechanics ripped me off $220 for it. It turned out to be
just some problem of grounding of the Crankshaft position sensor (pos).

 

yeah i guess people saw this too late, but its resolved, i learned a boatload int he process, i guess the best way to learn something it to try to learn from scratch. hope this post just helps someone else in the future.
