Aftermarket electrical parts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Tell me about your thoughts/experience on aftermarket electrical parts.

I've been throwing a code for over 10 years and have replaced almost every part associated with it. I started with changing the accelerator pedal position sensor for a p1125 and p2125. It worked initially but within days the problem resurfaced so I thought it was due to another issue. (When you rework your own harness and buy an engine off craigslist there's always doubt/questions.)

10 years later and a lot of intermittent down time not using the truck, I think I'm back to this part. It is a Dorman part. Now I'm buying a different company's part to replace this...fingers crossed.

With a lot of internet research I've heard some rumblings about using aftermarket parts. What say you?

Lately I try to buy AC/Delco parts for my other truck/cars. Sometimes that's not an option. Any specific companies you like/dislike?

2005 6.0L Lq9 with 4l60e
* Reworked the stock harness and used all the stock components, including maf, map, ecm, tac module/wiring, pedal position sensor, throttle body and sensor, o2 sensors

*Swapped out one at a time in this order: Dorman pedal position sensor, New tac module and it's wiring harness, APDTY throttle body sensor, Current Performance wiring harness with new Bosch O2 sensors, new Hitachi throttle body with sensor, and just now a new Standard Motor Products pedal sensor

We'll see if I get the same error code with the new pedal position sensor. Maybe a new sensor from the dealer if it happens again.

Otherwise, what's left? A NEW ECM, map sensors, maf sensor.

Anyways, more of a question as to success/failure with aftermarket electrical parts....

I buy parts online for convenience. I'm happy to pay extra for quality. I just don't have the experience to know which company has quality parts...

I had problems using Bosch O2 sensors. Replaced both with AC Delco and had no issues since.
