2013年8月17日 · The main code that continues to reset itself is the P0638 (001592) "Throttle Body Actuator bank 1" - Implausible Signal - intermittent - MIL ON They advised that I could drive the vehicle home (30 Miles) and they would do some research to determine the next steps.

2008年8月18日 · Edit How I did NOT clear CEL/MIL - Still Issues after replacing 03G 128 063T I had these two faults (below) which triggered a flashing glow plug light (GP Lt) on occasion, once every 3-6 months. This has been going on for almost two years, only after a cold start. It would always reset once I...

2010年8月1日 · Drove at lunch and home again in the evening, the light on the whole time, but engine seemed normal. This morning I ran errands, driving normally. The CEL light stayed on the whole time (but no other lights). I had the code read at AutoZone and got P0638: Throttle actuator control range/performance- bank1 Explaination: Failed TPS Probable cause:

2019年12月29日 · I've got a 2005 outback xt that will go into limp mode every month or two while throwing a P0638. Symptoms: -Idle hunting, rpms jump up and down -intermittant high rpm at low speeds/idle while off gas pedal - Limp mode about once a month With an obd 2 reader the throttle position moves up...

2005年11月9日 · Seems to me another new check engine code pops up weekly. Well, I love my 10' Jetta TDI Sportwagen but I am concerned. After 100K miles things are starting - Radio goes out, $800.00 to fix, DSG seems erratic, and so on. Now I get a PO 638 code. I am concern about taking it to the shop, another...

2012年8月24日 · New throttle body (FIAT recon unit) worked for 2000 miles or so, then P0638 returned intermittently. I have checked every conceivable wire to the unit, plus others that link to other items such as oil level control ecu (on bracket for main engine ECU). Tried earthing individual wire to throttle body earth = fault still occurred.

2018年5月8日 · Sitting on the side of the road, waiting for the roll back. Car just quit accelerating. Felt like a throttle cable snapped. CEL came on. Was able to coast to a safe spot with the engine running, albeit a bit rough. Pulled my code scanner and got P0638 which is a throttle position code for bank 1. Where should I start looking once I get it home?

2016年12月21日 · And last night, I started the car and immediately got the flashing glow plug light. I was able to drive home without any of the symptoms others have described (unable to throttle, slow pickup, limp mode, engine shudder, etc.) It …

2010年2月13日 · Just an FYI - I experienced flashing glow plug and check engine lights with a service now message in the center display. I scanned the car with VCDS and found the p0638 code below. The dealer is replacing the throttle body and said it's covered by the extended warranty from dieselgate. My car is...

2014年11月3日 · On two of the occasions MultiECUscan has logged the P0638 fault at idle speed and when the engine isn't far off cold (35C), so I'm guessing it happens at a junction or roundabout about 5 or 10 minutes after the first startup of the day.
