SOURCE: Failed Smog Test - 4 codes for 2001 Isuzu Rodeo

Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.

this is the most common error code, just means the one of the nods in fuel pump misfired, on every model other than the ones for usa market, after clearing the error code on vcm the check engine light would reset. for our cars its programmed to stay on.

it will not effect the running of the car or its performance

SOURCE: check engine light on-code says egr valve is bad

the egr system consists of control circuits as well as the egr valve itself. troubleshooting will have to be performed in order to pinpoint the fault. the valve may just need cleaning. there may be damage in the long run since the egr system introduces exhaust gas to the air intake to reduce combustion temperatures.

How do you clear check engine light on 94 jaguar xj6 after getting fuel fail code 14


First off, you might need to actually have your engine checked. However, if you know that the engine is in good shape and you're still seeing that pesky check engine light in your Jaguar XJ6, here's a cool trick for how to turn it off.

  • Remove the passenger's side dash liner.

  • Look for the round red connector with a single pink/red wire that is hanging free.

  • Turn on the ignition but do not start the car and then press the VCM button.

  • When the code displays, use a jumper wire to short the pink/red wire to ground for 3 seconds.

  • Turn the key off for 10 seconds and then turn it back on and check for any more stored codes.

  • If there are more use the same procedure to clear them.

What does the check engine light vcm code "fuel 14 /fail 14" mean on my jaguar xj6?


this has to do with the engines ability to warm up and meter the fuel. either the thermostat is sticking or the coolant temp sensor is out of range. there are 2 of them at least, one for the guage and one for the pcm. if you find it is the t-stat sticking, replace with jaguar parts.
