1996 Corolla DX, 1.8, 198K miles

 

 

The CPS has gone bad, again! This will be the 3rd time I have had to replace it!

I bought a new one from AZ, with a lifetime warranty, then it went bad. Now I have to replace it again. What could be making them go bad? I'm sure some will say AZ Duralast parts are a POS, which I agree with, somewhat.

Any ideas why the CPS is going bad? I have some ideas in my head but want to hear from the pros here. Thank you!

I pulled out the sensor and just as I thought, there is oil on it. I'm guessing my crankshaft seal is leaking or oil is leaking from elsewhere too. Could the oil be the culprit as to making the sensor go bad?

Yep, I have to agree with you. But, it's my sons car and he's footing the bill. He says if it goes bad again he will just go back up to AZ and get another one, just like he has got the last (2). It's installed now and runs good as new, until this one fails.  :rolleyes:

About the only time i ever use Auto Drone parts is if i need something in an emergency, and the other name brand parts stores do not have said item. Or it is after hours, and i can not get it OEM from a dealership.

 

I just changed out a failed Auto Drone battery. I installed this battery back in 2009. Luckily, there still was a little bit of a warranty left on it. But my point is who cares about a warranty, if you have to keep using it? This isn't the first time i have had a Auto Drone battery fail on me either.

 

One would think you could go just about anywhere to get a decent battery these days. I mean, how many different battery makers are there?

 

And besides, you wouldn't want your son to have another sensor failure, possibly driving through a 'hood like mine, would you? Unless he can run like O.J. did in those Hertz rental car ads from the 1970's, and or owns a .357.)

KP, I understand what you are saying. But I can tell this to my son until I am blue in the face, and his selective hearing kicks in. If he is willing to go another 15-20K miles and do this again, so be it. One day he will understand.

Can't help anybody that can't help themselves. Aftermarket engine management parts have always been a problem. I think you answered your own question.

I guess I'm lucky, in that aspect. I have a daughter who actually listens whenever I offer her any "car" advice.

That's good that she listens. :)

I told my son when his friend changes his timing belt to also replace the water pump, thermostat, and crank seal. I also suggested that he start using a HM 10W40 oil to try and slow the leak down. Well, he actually listened to me, but, now the leak has slowed down and he is putting off the timing belt and such. I guess he will have to learn the hard way.

This reminds me of my ex co worker. I sold him my Ford Escort when I bought my Pontiac. Every spring afterwards he was changing out the front hub wheel bearings in it. I asked him what gives? I only changed one when I first bought it. Come to find out, he was a price shopper. If Auto Drone was the cheapest when he needed them, he put in the order. If E-Bay was cheaper, he went that route.

 

The next year they failed, I took him to the Ford store I deal with. When he found out that he could only buy 1 side bearing from Ford for the price of 2 Auto Drone bearings, he left the Ford store and went back to Auto Drone. I told him I am DONE helping him..............

Yeah, but VatoZone offers a "lifetime warranty", KP. You bring it back, and they shoot you.

 All jokes aside, I recently discovered my Impala has a designed-in problem with brake rotor warpage. (4-wheel disc). So, I went over to our local VatoZone and bought a set of their "Premium Quality" brake rotors....with a lifetime warranty.Lucky me....So far, I've had my friends at VatoZone replace all four brake rotors on my car for free.....5 times. And....I've still got my "lifetime warranty"

As Blazin' would say, "BWah, hah, hah, hah,ha!!

I keep taking my worn out brake pads back to Auto Drone for the free replacements every 40K. Since I put close to 20K a year on it, I have saved myself a lot of dough doing it this way. Screw them. Give me a warranty? FOOLS! I will hold you to it.)

 

As far as the rotors go, I suspect you need the drilled and slotted ones I got years ago. Yes, you will drop some coin on them. But they usually will last until you are ready for your next ride. Remember, everything in a Auto Drone store is Chinese. Except for the help. Those are made in Mexico.
