Code P0403 Came up on computer, would that cause engine tapping?


code p0403 refers to exhaust gas recirculation (ERG)--circuit malfunction===causes wiring--EGR solenoid---ECM. The tapping you are hearing is detonation due to incorrect ignition timing or air- fuel is wrong for the rpm of the engine. It is an uncontrolled ignition of the mixture in the chamber and will do damage to the engine it not fixed.. The EGR valve is used to re-introduce exhaust gases into the combustion chamber to stop the detonation and to burn the unburnt exhaust gas. So yes it will cause your problem and should be replaced.

Grand carvan gives p402 code


This is not a cut and dry fault code. This means that more than one thing wrong can set the code in the computers memory. Here is the low down on the P0402 fault code. This is from the OBD2 fault code diagnostic book.

P0402 - Exhaust Gas Recirculation Flow Excessive Detected
Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible engine hesitation
Possible causes - EGR solenoid valve harness is open or shorted
- EGR solenoid valve circuit poor electrical connection
- EGR volume control valve stuck closed
- Dead (Weak) battery
- Faulty EGR temperature sensor and circuit
- Faulty EGR Valve
- EGR passage clogged
- Exhaust gas leaks

What is wrong with the car it shows me p0432 code main catalyst efface below threshold (bank2), how do I fix it cause the engine light goes on and stays on?


Hi.

The code means what it say. The car computer compared the data on amount of air/fuel injected in cylinders with the emission O2 reading from the Oxygen sensor in the air intake (the one after cat converter), and decided that the catalytic converter is not doing its job because emission is too high.

In some case the problem is occasional. Try resetting codes by disconnecting battery terminals (make sure you have stereo code if needed).

If the code comes back, then there are several parts to be tested before replacing cat converter.

Many times the problem is the converter itself. before replacing the converter the mechanic must check for problems resulting in wrong air/fuel mixture, as these may trigger p043.

Sensors in the air intake and air intake itself must be tested, check MAP sensor and intake structure for leaks. Replace air filter. Check the vacuum for leaks. Check IAC. Check O2 sensors.

If there is no problem under the hood, check the state of other parts comprised in the exhaust system and eventually replace the cat converter.

Regards.

IHAVE A 1991 JIMMY GMC I HAD TUNE IT UP PUT A NEW CAP AND ROTO PLUG AND WIRE AND CHANGE THE FUSE FILTER ALSO BUT IT KEEP CUP OFF WHEN I MAKE ACOMPLETE STOP AND WHE IAM RIDE WHAT COUL IT BE.


3 most common causes for your problem are:
  1. Bad EGR (Exhaust Gas Reciculation) valve - clogged EGR will cause engine to stutter or miss
  2. Bad MAF (Mass Air Flow) sensor - will also make an engine stutter when bad
  3. Bad TPS (Throttle Postition Sensor) regulates idle speed under multiple conditions.

Check engine light code came up p2101 throttle actuator control moter ciruit range/performance whats this mean/ whats the fix thanks engine lost power dash said reduced engine power let it set for 20 min...


There is either a high or low circuit problem with the motor. The ecm, or called the computor, moniters the cuircuit for the motor.
The best thing to do is have the control motor checked and the ecm. One of them is bad.

Exhaust gas reciculation flow


Below is a link to the EGR (exhaust gas reciculation) valve on your car.

http://www.chiltonlibrary.com/content/images/9115/images/91154p25.gif

Here are instructions on removal:

  • Disconnect the negative battery cable.
  • Unplug the electrical connector from the EET.
  • Detach the vacuum hose from the EET.
  • Remove the EGR valve mounting bolts, then remove the EGR valve and EET.
  • Remove and discard the old gaskets. Thoroughly clean the gasket mating surfaces and/or passages.
  • Check for any signs of leakage or cracked surfaces. Repair or replace as necessary

    Best of luck on your repair.

    I have a 1997 suzuki sidekick jx it did not pass smog the data trouble codes are p0300 random multiple cylinder missfire detected, p0400 exhaust gas reciculation flow. how do i fix?


    In this case you need to take a look at your EGR Valve and Solenoid. I would check with your local auto parts store to see if they check those for free (some do and others charge a small fee). Most likely you have a bad EGR Valve or EGR Solenoid. Hopefully this gives you some direction. Thanks for using FixYa!

    Sincerely,
