What does the p1404 code on a Chevy mean?

On some models, there is a service bulletin for the P1404 code that suggestss reprogramming the Powertrain Control Module (PCM) to repair the problem. The cost to diagnose the P1404 CHEVROLET code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.

What does p1404 mean in Powertrain Control Module?

P1404 Meaning. The Powertrain Control Module (PCM) determines that the EGR valve is stuck open if the actual Exhaust Gas Recirculation (EGR) position and the learned closed EGR position vary by more than a predetermined value.

What causes the VCM to set the p1404 DTC?

SEVERE OCCURRENCES MAY CAUSE THE VEHICLE CONTROL MODULE (VCM) TO SET A P1404 DTC BECAUSE THE VCM PERCEIVES THAT THE EGR VALVE IS STUCK OPEN. 1. USING THE TECH 2 SCAN TOOL, EXERCISE THE EGR VALVE, AND VERIFY THE [EGR] VALVE’S ACTUAL AND DESIRED POSITION TRACK.

Can a vehicle set a false OBD II DTC p1404?

SOME VEHICLES MAY SET A FALSE OBD II DTC P1404. ELECTRONIC NOISE IN THE VEHICLE MAY CREATE MOMENTARY FALSE “LOW” EXHAUST GAS RECIRCULATION (EGR) PINTLE POSITION FEEDBACK SIGNAL VALUES.

Is there an OBD code for exhaust gas recirculation?

SPECIAL NOTES: OBD II code with the definition “IAT [Intake Air Temperature] – B Circuit Malfunction / Exhaust Gas Recirculation Closed Position Performance” is mostly relevant to some General Motors (and a few European) products from the late 1990’s to the early / mid 2000’s, and is therefore no longer in common use by most manufacturers.

Are there any problems with the GM LB7 engine?

As impressive as GM’s new engine platform appeared, the LB7 had terrible problems with fuel injectors failing. In fact, injector failures were so frequent that GM was forced to recall the poorly designed units and replace them with an updated design.

What is the OBD 2 fault code p1404?

OBD II fault code P1404 is a manufacturer specific code that is defined by General Motors (Chevrolet in particular) as “Exhaust Gas Recirculation (EGR) Closed Position Performance”, and is set when the actual position of the EGR valve pintle does no coincide with the position of the EGR valve pintle the PCM (Powertrain Control Module)…

What does p0404 mean on an EGR sensor?

Often times code P0404 does not actually indicate that there is something wrong with the EGR valve itself, but actually that the EGR sensor is telling your PCM that the proper amount of EGR needed to flow back into your cylinders and cool them is not present.

How much does it cost to repair a p1404 Chevy?

An error occurred while retrieving sharing information. Please try again later. What does this mean? The cost of diagnosing the P1404 CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.

Why is my p0404 exhaust gas recirculation not working?

The actual EGR position should be very close to the “desired” EGR position. If it is, then the problem is likely intermittent. It may have been a lodged piece of carbon that has since dislodged, or it could be a bad EGR valve winding that intermittently opens or shorts as the valve temperature changes.

What kind of EGR valve does a p0404 have?

If you have a P0404, then the EGR valve is likely an electrically controlled EGR valve instead of a vacuum controlled EGR valve. Also, the valve will usually have a feedback system built into it that informs the PCM (Powertrain Control Module) what position the valve is in; open, closed, or somewhere in between.

Why does the PCM set the p0404 code?

The PCM sets the P0404 code if the error is too great. An Exhaust Gas Recirculation (EGR) system is used in order to lower Oxides of Nitrogen (NOx) emission levels. The EGR system accomplishes this by feeding small amounts of exhaust gas back into the combustion chamber. High combustion temperatures cause NOx.

What are the symptoms of the p0404 trouble code?

What are the symptoms of the P0404 code? 1 The Check Engine Light will be illuminated and the code is set in ECM memory. 2 The engine may have pre-ignition on acceleration. 3 The engine EGR system can cause the engine to run rough, hesitate or even stall if it is not indicating the proper EGR valve position to the ECM.

How much does it cost to repair a p0404 Chevy?

Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost of diagnosing the P0404 CHEVROLET code is 1.0 hour of labor.

What does service engine soon warning light p1404 mean?

Engine Light ON (or Service Engine Soon Warning Light) P1404 Meaning The Powertrain Control Module (PCM) determines that the EGR valve is stuck open if the actual Exhaust Gas Recirculation (EGR) position and the learned closed EGR position vary by more than a predetermined value.
