Voltage sag on warm start
Ronnie38 replied to KK911C4's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
first when engine is hot measure the voltage on the battery post in the engine bay, then the alternator battery post the difference of the readings is the loss across the Y, or if nimble positive lead to the alternator and negative to the battery post this will be the drop. This will be the maximum the battery will charge to, remember 13.8 is a fully charged lead acid battery. -
I have had both rear windows on my 2001 C4 CAB go bad I replaced the drivers one with a new one, The passenger one I just replaced the cable, gear and pully but it just failed again after a year. I will order a new one now, cheap is not always the best.

I agree it only takes a waif of oil to coat the thermistor, also use the correct method to clean the MAF
-
yes we did, level at temp after fill to top off and still running when plug installed 4 times once to change filter, then replacing speed sensors, replace valve body then recheck after test run.
-
thanks for the info. It's 60 miles to the nearest dealer, so I was trying to fix it myself, will ohm out the wiring then try controller then change the clutch packs.

MY2001 911C4 CAB : Had slippage in 3rd when making a 90 degree turn as it shifted into 3 underpower. Ah I though low fluid so I changed the filter and the oil yes Porsche type. Now if I drove it right (go like a Porsche) and so 3, 4th then flashing indicator and limp mode. Took it to an Indy Porsche mechanic, replaced valve body input output sensors, worked on it for 3 months gave back no charge couldn't fix it. So I have been driving it in manual shifting at 2200 RPM works fine if I go to 2700 RPM bingo limp mode. The P0717 just; showed up today as I pushed it. The P0717 on line checking said the control module or ground fault. Anyone out there can help? Don't want to throw money at it and buy a control module.

P0733 and P0734

I just got back from San Francisco, the car sat since Nov 20th. Jacked it up leveled it ran it till 80 degrees C while running in park opened check port and fluid ran out I let it run out till it stopped. So I don't thing low fluid was a problem. Rolex start next week, if I run it and it goes into limp mode will it hurt driving it? If I turn of the car and restart the limp mode goes away for a bit than in heavy traffic or stopping at a light it will come on again. I'm 11 miles from the speedway. -
I wish to thank you, I did not know that the crows foot had to be at a right angle, got to replace the front boots.

Had same problem, removed right front wheel, pulled back plastic well liner found the cable, then had the alarm module refurbished and ordered the waterproof box from the ECU Doctors but when out of country pull a trickle charger into cigar lighter just be be safe.

P0733 and P0734
Ronnie38 replied to Ronnie38's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)
yes double checked after codes showed up since the Druamatic cannot read this transmission used infrared temp gage on the pan, used level on door sill to ensure car level. -
My 2001 C4 Automatic had what appeared to slip (over rev) when making scarp turns, decided to replace transmission filter and refill, the first run after 10 minuets the transmission went into limp mode (lights on drive selector started to flash) check engine lamp came on (P0734 and P0734) was read. the reason given was input and output ratio wrong for both codes. The Durmatic gave no other info. So I proceeded to order both input and output sensors. Since I couldn't confirm if a shift selonod was bad. Mean while I am in Cal for the holidays I remembered I moved two of the magnets in the pan there were 4 magnets 2 each in the depressions in the rear of the pan I took one each and moved the forward closer to the input and output sensors. Anybody out there have any idea besides taking it to the dealer, at 75 bucks for the 5 liters of tranny oil each time I replace something to help me be smarter?
