Emission 3 codes can up p0403 p0700 p1776 what does it mean


You only have one code that is connected to emissions and that is P0403 which is the egr solenoid, this is usually connected to the EGR which is usually on the engine back by the fire wall towards the master cylinder side. The solenoid has one or two wires and sometimes on top of the EGR valve or right near it. The other two codes have to do with the transmission and should be taken to someplace like AAMCO transmission shop where the transmission should be checked and the codes cleared. I hope this helps.

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.

Hi there:
P0403 - Exhaust Gas Recirculation Circuit Malfunction



The most common failure is the EGR solenoid goes bad. The code will not set and turn on the light until the car's computer has gotten around to completing the EGR self-test.

The P0403 indicates the computer is not seeing any voltage on the blue wire coming back from the egr solenoid.


With the ignition on and engine off, use a scan tool to activate the EGR solenoid. Listen or feel for a clicking, indicating that the solenoid is operating.

If the solenoid does operate, you'll have to check current draw on the ground circuit. It should be less than one amp. If it is then the problem is intermittent. If it isn't then there is excessive resistance in the circuit and perform the following

1. When it's activated see if you can blow lightly through it. IF you can\'t there may be a blockage causing excessive resistance. Replace EGR solenoid as needed. If there is no blockage, disconnect the EGR solenoid and the PCM connector containing the EGR solenoid control circuit. Using a digital Volt-Ohm meter (DVOM) check resistence between the control circuit and battery ground. It should be infinite. If it isn't, then there is a short to ground on the control circuit. Repair the short to ground and retest as needed.

2. If the solenoid doesn't click as it should, disconnect the EGR solenoid connector and connect a test light between the two wires. Using the scan tool, command the EGR solenoid on. The light should light up. If it does, replace the EGR solenoid. If it does not perform the following: a. Check for 12 Volts on the ignition supply voltage to the solenoid. If it isn't present, inspect the supply circuit for an open, or a short due to chafing or breakage and re-test. b. If it still doesn't operate: then manually ground the EGR solenoid control circuit. The light should light. If it does, repair open in EGR solenoid control circuit and re-test. If it doesn't, replace EGR solenoid.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
