Might still be under warranty. P0420 is a catalytic converter efficiency code. Usually this means the catalytic converter is no longer able to do it's job. The computer knows when it is failing and sets this code.

Check with your dealer to see if the catalytic converter might still be covered as it is an emissions component.

07 dodge caliber cranks won't start no spark changed crank sensor still won't start

I need to know what fault codes you have in the memory of the powertrain control module. Also which engine you have. If you have not run a fault code test rent a code reader and do the testing, the diagnostic link connector is under the dash on the drivers side.

Nissan Tida 2008 P0240

Some cars require that the onboard computer be cleared of the past error reading. The error reading may cycle out on its' own after 35 or more starts, but some can linger.

If the driveability issues remain, then something else may be at fault. If no driveability issues, then you just need a reset.

Now my information shows a different result for Code 240. There is a problem with a Turbo boost sensor if you have a Turbo on your car.

How to clear code 118 and 224 on 1994 ranger

Ford Ranger/Explorer/Mountaineer 1991-1999
Clearing Codes



These codes are retained in memory for 40 warm-up cycles. To clear the codes for the purposes of testing or confirming repair, perform the code reading procedure. When the fault codes begin to be displayed, de-activate the test by either disconnecting the jumper wire (meter, MIL or message center) or releasing the test button on the hand scanner. Stopping the test during code transmission will erase the Continuous Memory. Do not disconnect the negative battery cable to clear these codes; the Keep Alive memory will be cleared and a new code, 19, will be stored for loss of PCM power.


The Keep Alive Memory (KAM) contains the adaptive factors used by the processor to compensate for component tolerances and wear. It should not be routinely cleared during diagnosis. If an emissions related part is replaced during repair, the KAM must be cleared. Failure to clear the KAM may cause severe driveability problems since the correction factor for the old component will be applied to the new component.
To clear the Keep Alive Memory, disconnect the negative battery cable for at least 5 minutes. After the memory is cleared and the battery reconnected, the vehicle must be driven at least 10 miles so that the processor may relearn the needed correction factors. The distance to be driven depends on the engine and vehicle, but all drives should include steady-throttle cruise on open roads. Certain driveability problems may be noted during the drive because the adaptive factors are not yet functioning

I replaced the sensor and cleared the code and the light came back on any idea what else could be wrong?

You ask a question,obviously never read it.

What vehicle are we talking about?
What were the problems or driveability issues?
What was the code?
Why did you change a sensor?

Codes don't tell you what is wrong or what to change.

2005 jeep grand cherokee limited 5.7 hemi vehicles hesitates

The egr valve is located on the front of the right cylinder head. It has a tube attached to it and going to the intake manifold.It has failed and is why your jeep is running rough and hesitating. Replace it and it will fix your driveabllity issues. Disconnect the battery for 2 min to clear the code.

2 codes show up on the reader.

The P0341 code is a code indicating that the cam position sensor circuit is out of range or not performing properly. The P0404 code indicates the EGR is out of range or not performing properly.

Those codes seem rather odd to have together. If the cam sensor was bad I would expect some driveability issues or possibly even issues with getting the vehicle started. The EGR could cause some idle issues.

I just cant get past that those codes seem so unrelated, they are for two different systems. If you are not experiencing any driveablity issues, I would clear the codes with either a scan tool or just disconnect the battery for a few minutes. If they come back then yes, I would have it looked at. You could try replacing the Cam position sensor, and see if that helps, but the EGR is a bit more challenging and would be a more costly item to replace.

Hope this helps out.
