you should have a input sensor and a output sensor on the driver's side of the trans!!
they are common to go out on these intrepids!!!

P0420 - Catalyst System Efficiency Below Threshold (Bank 1)

The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.

Symptoms: You will likely not notice any drivability problems, although there may be symptoms.

Causes: A code P0420 may mean that one or more of the following has happened:
* Leaded fuel was used where unleaded was called for
* An oxygen sensor is not reading (functioning) properly
* The engine coolant temperature sensor is not working properly
* Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
* Retarded spark timing
* The oxygen sensors in front and behind the converter are reporting too similar of readings

Possible Solutions: Some suggested steps for troubleshooting a P0420 error code include:
* Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
* Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
* Inspect the downstream heated oxygen sensor (HO2), replace if necessary
* Replace the catalytic converter

One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.

Fig. Removing and installing HO2S1-3.8L Engine

Finally, YES, I suggest replace the O2 sensor; the heated oxygen sensor may be difficult to remove when engine temperature is below 120°F (48°C). Excessive force may damage threads in exhaust manifold or exhaust pipe.

Good luck.

Tranmission problems


I assume this is an automatic transmission? (Otherwise, you control the shifting...)

Your transmission gears might be worn. You should take it to a reputable mechanic.

Automatic tranmission not working on overdrive, tacoma 2006


The knock sensor fault may be preventing the transmission from shifting to OD. The main engine computer also sends commands to the transmission computer. Your transmission valve body is controlled by electronics.

Problems with ignition key wont turn on


Had same problem on my 2000 Impala and my 2001 monty carlo on the impala it was the locking mechanism from the transmission was slightly worn there is an adjustment under the dash to lengthen the pin slightly. The monty I had to change the ignition switch behind the key. U can try alittle light oil or WD 40 in the key hole it may help. Ignition and switch not cheap. It is not too hard too change if your a little mechanical and have a couple hours.
