TJBaker57 replied to the thread "Check Gages" light, oil pressure at 0.The oil pressure SWITCH threads are M16 x 2 -
I only noticed the light when I pulled in after a short half hour trip. All other gages were normal so temp was right about the 210 location, and this was at idle.

TJBaker57 replied to the thread "Check Gages" light, oil pressure at 0.Well allow me to rephrase... MY Tech 2 on MY 2002 4.2 does not display "oil pressure". I have tested a few oil pressure switches from the 4.2. They are a basic ON/OFF (open/closed) device...

I recently had to repair the recirc actuator (I didn't replace it, I repaired it by taking it apart and installing roll pins, documented elsewhere here). Here in Arizona it's almost a requirement...

TJBaker57 replied to the thread "Check Gages" light, oil pressure at 0.No scantool can read oil pressure for the 6 cylinder 4.2 engine as there is no sensor that can read that. Query: What was the engine temperature when this warning came and what was the engine rpm?

TJBaker57 replied to the thread Front Defroster Suddenly Ticks.My recirc has been broken for more than 10 years. I don't consider it worth repairing. However, I live in a very dry climate and get as low 32° F out of my A/C system.

TJBaker57 replied to the thread Front Defroster Suddenly Ticks.Are you aware of what the recirc actually does?? The sole action of the recirc is to allow air from outside the vehicle to be drawn in or not. It has absolutely zippety-do-dah to do with where...

TJBaker57 replied to the thread Engine Dies at 40mph 1500rpm and 140 degrees....Correct. The inline fuse I mentioned was only for the sake of of explaining the issue I had with the TransAm. And how a bad connection can cause an intermittent loss of connection during a warmup...

Like.
I think you have an electrical issue... potentially powering of the PCM. The "check engine" should be coming on. As tjbaker57 has stated, check powering and grounds going to the pcm.... maybe... -
TJBaker57 replied to the thread Front Defroster Suddenly Ticks.Personally, I would begin by replacing BOTH the MODE and the DEFROST actuators. These are the two that control where the airflow goes AND they are the easiest to do. They are right next to each...

TJBaker57 replied to the thread Engine Dies at 40mph 1500rpm and 140 degrees....FWIW, I suspect something electrical. Perhaps something like a PCM ground or similar critical circuit without which the engine cannot run. I had an 86 TransAm, bought new, It sometimes would...

TJBaker57 reacted to krunal88's post in the thread SOLVED! Washer and wipers turn on when truck started with Like.
So to finalize, I ended up getting a new old stock Valeo wiper motor from good ole eBay. Part number 15094704. I ended up just swapping on the pulse board from the new motor onto the existing...

TJBaker57 replied to the thread NEED HELP 05 Trailblazer Fuel Gauge Problem. Bad PCM?.That may be stepper motor failure? I cannot say for sure as I have never personally seen stepper motor failure. When the key is first turned to RUN do the gauges all sweep counterclockwise towards...

TJBaker57 replied to the thread Temp Actuator position ranges.FWIW I think that only the Automatic Control systems have temperature sensors. The manual control versions have none.

TJBaker57 replied to the thread NEED HELP 05 Trailblazer Fuel Gauge Problem. Bad PCM?.Are you asking about PIDs 1155 and/or 002F ?? I have a 2006 PCM and at least on that unit both fuel level PIDs 1155 and 002F are supported. It is important to note that they report different...

TJBaker57 replied to the thread SP206 Pinout info, please.I continuously struggle to follow these automotive schematics myself. I've gotten a lot better at it in retirement over the past 5 years or so. My experience outside of the automotive environment...

TJBaker57 replied to the thread AC not blowing cold but Gauge pegs into red area indicating there's freeon in sys..FWIW, those that have an OBD2 adapter and an app that reads live data PIDs.... You may be able to read the high side pressure with a custom PID entry. It very likely will not be included with...

TJBaker57 reacted to Mooseman's post in the thread AC not blowing cold but Gauge pegs into red area indicating there's freeon in sys. with Like.
You need a two gauge setup. The low side will show higher pressure when the compressor is off and then drops. To me, that looks like it's under charged or there is a severe blockage preventing...

TJBaker57 replied to the thread SP206 Pinout info, please.Per the zoning diagram any electrical ground, splice, harness, etc that begins with "2" is located in the dashboard, NOT the main cabin. "SP206" is a typo.

Even in the 80's the world was already creepy. I was installing complex medical x-ray systems starting in 1982. The first microprocessors were coming in, and we had to program them by flipping...

TJBaker57 replied to the thread SP206 Pinout info, please.The lower sketch in the previous link is the data bus splice pack under the rear seat. The upper sketch in the previous link shows the splice pack in the lower dash...

TJBaker57 replied to the thread SP206 Pinout info, please.For this serial data bus there is no "sorting" of the signal. Every module receives every message. Each module even listens to its own message pulse as it sends it.

TJBaker57 replied to the thread SP206 Pinout info, please.This may be a typo in the diagrams but here is SP 306...

TJBaker57 replied to the thread SOLVED! Washer and wipers turn on when truck started.My 2002 without any rain sense option also suffered that same stuttering behaviour. Same solutuon, opening up the works and cleaning those rings/contacts.
