My 1999 Olds intrigue shifts fine until it warms up, then goes into limp mode. Disconnected the coolant temp sensor and put a new one on the wires and left outside the engine. No change. Please help!

Run the fault codes as the limp mode is from engine AND transmission faults
the problem could be in the transmission servo/ solenoids or TCM

Some of these have two temp sensors, one for the gauge, and one for the computer.

Hi....
In your Intrigue to use the New Passcode sensor .
You need to program the new Passcode to the ECM. of the Vehicle.
This is a prosses that involve around 30 minutes maybe a little more.

Remove the old Ignition switch.
Install the new Ignition switch. with the new Passlock sensor.
Turn the key to on position and try to start a few senconds. them leave the key on run position.
For 10 minutes and NOT more than 11 minutes.
Them turn the key to OFF position for exactly 30 seconds.
Them turn the key to Run position 10 minutes or 11.
them turn back the key to OFF position for 30 seconds.
Them turn the key to Run position 10 minutes or 11,
Turn the key to OFF position and wait 1 minute, them try to start the vehicle.
If the car start you are DONE.
But if Not Letme know to give you more information.

OK I hope this help to try solve your problem.

Thank you for use fixya...

SOURCE: limp mode on a automatic

Firstly, disconnect the battery and leave it for a few hours. Reconnect and try the car again. This resets the memory in the TCM. If the car picks up the faults again, it will go into limp mode again after a short while. If it's been a while since you changed the fluid, then put some seafoam transtune in to clean all the parts and plates. Then after a few days at least, preferably a week, go for a fluid and filter change. After this, you'll probably find it will go into limp mode again, just disconnect the battery again and reconnect after a few hours. I had the same problem in my chrysler T&C. I left seafoam in it for a week and it cleaned up all of the gum and varnish build up on the shift solenoid pack and plates.

If the problem persists, and after you find it allows you to change gears for a while and then goes into limp mode, it could be gummed up solenoid pack, or input speed sensor.

Go to o'reillys and plug in their diagnostic tool. It should provide you with the fault codes if any. If no codes, then your TCM and ECM are in good shape, and if you're lucky then it'll be something simple like a sensor, or solenoid. Try cleaning it first with seafoam transtune in the fluid for a week.

If all else fails, and their are fault codes, then take the car to a trusted transmission repair shop for a road test. The computer could be picking up slippage and making the car go into limp mode. This could be the clutch plates if no errors with the TCM, ECM are present, and you've ended up checking out the input speed sensor, and solenoid pack. The latter can cause hard shifting and slippage too, if the seed sensor is set to signal when to change gear, but the new oil, or old oil have made the friction slightly different to what it is used to or within factory limits. Firstly try reseting the TCM by disconnecting the battery for a while and see what happens.

Good luck

check that the EGR valve is not sticking or has a vacuum leak. This valve will not operate until the engine is warm.

check also the engine coolant temp sensor (ECT). This sensor tells the engine computer that the engine has warmed up, so if it is faulty, it could be sending wrong information to the computer. If the sensor is disconnected, wires to it broken, or faulty in full cold mode, it will tell the computer that the engine is very cold, like -40F. The computer will schedule fuel for cold conditions. This is usually way too much fuel for a warm engine and it will rich misfire, idle rough, and be difficult to start warm.

The ECT has two wires going to it and is dedicated to sending information to the engine computer. It has nothing to do with your dash gauge that shows coolant temp. That sender has only one wire and is dedicated to the coolant temp gauge.

You could also have a bad battery. If it's putting a strain on the charging system, it will undervolt the whole system. And you need an OBDII sensor reader to get rid of the shifting problem. Your transmission went into limp home mode because of the undervolt. Disconnect the battery for a couple minutes, reconnect the battery and restart the car. Then disconnect the negative cable while the car is running. If the battery light goes off with the cable off, your battery is bad. The problem with electrical devices is that when one thing goes bad, a lot of things go bad because of the first thing. If that doesn't help, take your alternator back to where you got it and have them test it.
