Have a 2001 v6 oldsmobile 3.5 that drives great, except on cold days when i start my car up at night sometimes the check engine light comes on and i scan it the code reads p340 any suggestions?


Have a repair shop diagnose the PO340
Cam Sensor Fault Code

Doesn't mean the sensor is bad

Find out why it reported to code

If the shop compares the cam sensors
to ignition timing on a V6 ,the events have
to occur at 120 degrees for each cylinder,
when viewed on an oscilloscope

Engine light on when cold off when hot around 81 degrees or higher


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

The heat/air Temp reading is blinking.....when this happens we loose heat. If the car is restarted the problem is corrected for about 20 sec, then the temp blils again, and the heat is lost.


There is a problem with your Automatic Climate Control System. You need to check the system for fault codes and diagnose the system for the code or codes that you get.
The information that I have says that the codes in this system can only be retrieved by GM's Tech 1 Scan Tool. (Nice little feature that GM added to force people to take their cars to the dealer for repair)

This is a classic case of why I personally support the Right To Repair Coalition.

Overheats while Idling.


there are 3 cooling fan reays in a 98 aurora and they are computer controlled. the low speed fan relay should turn on when the ecu detects a temp of 229 degrees and should turn off when the temp has dropped to 216 degrees. it is best to check the temp with a computer monitor so you can see what the computer is reading. If you turn the a/c on you can see if the fans are operating. If they don't come on with the a/c you may have a problem with the high side a/c switch. A bad thermostat can cause the fans to come on late.

Air conditioner clutch will not engage. also my car has auto climate control and the external temp. light always reads 30 degrees.


That is why the A/C clutch is not coming on.If the temp is below 50 degrees the auto control will not allow the compressor to kick in to protect the compressor.You have to check the codes for the body control module.It should show a code for the outside temp sensor.You could have a bad sensor or wiring.If you disconnect it it should show -40 degrees.check wiring and connections.Hope this helps.Good luck.

My climate control starts blowing hot air while a/c is on


Make sure you have fully charged AC sytem first, if so Im sorry to tell you this but this is a difficult deal.you may not be able to correct this without taking it to a repair shop with gm scan tool. Reason being the actuators for the hvac that most likely are malfunctioning from either them or another component being bad , require recalibration.The other reason would be the body control module related.It would have to be scanned for U codes which can effect the hvac control.Sorry but thats what I know.

Onboard Temp gauge


This probably occurs when you start up after the engine has been off for a few hours. What is happening is that the module is taking a new temp reading however heat from the radiator is causing the sensor to read a warmer value than it really is. I suggest that you relocate the temp sensor further away from the radiator and closer to the grill opening in order to read actual ambient temp (approx 6" should work).
