2005 toyota corolla 1.4 d4d Sudden power loss

[Flataas90]

Hi all,

I drive a 1.4 d4d Corolla. Today on the highway my car suddenly lost all power. By that I mean I continued at the same speed but when I put the gas pedal to the floor, I got no reaction/acceleration just black smoke from the tailpipe. There was nothing telling me something was off, no warning lights or weird sounds. I tried gearing down but the problem was still there. However, If I engage the clutch and press the gas pedal the engine revs to 4500rpm without any issue. After I reved the engine to 4500 rpm while engaging the clutch, the problem disappeared for some time (5-15min) before it happened again. After “fixing” the problem this way 3-4 times during my way home the “trick” would suddenly not fix my problem any more. So, I turned on and off the ignition while driving to see if that would help. The problem persisted. Reved it to 4000RPM again and it was suddenly gone until I got home. Parked my car and it ideels just fine and I don’t have any staring issues. Checked for codes put the only code appearing was a historical Airbag fault code. The fault reading was done when the problem was not occurring. Google tells me that it could be EGR, Turbo boost sensor, Mass air flow sensor (MAF), suction control valve (SCV) or Even gas pedal position sensor.

Any ideas where to start? I think that the EGR is the easiest way to diagnose. But I’m not sure. Moreover, I understand that the SCV is also a common problem on the D4D motors. But I’m not sure if the 1.4 D-4D (1ND-TV) engine has the same type of fuel supply system as the 2.0 d4d engines and has the same problems?

Any solution

Hi!

I have exactly the same problem with my 1.4 D4D Corolla.

Please answer if you got any solution!

Aloha!

Okay i got a solution about this problem.

It was two things that caused it.

1. Dirty MAF sensor.

2. Dirty and almost completely stuck EGR valve. 

My car mechanic cleaned out those two things and my car works perfectly again. 

This no "accceleration pedal reaction" not the fault itself but its consequence, called: emergency mode.

Cleaning the MAF sensor, the EGR, EGR cooler, throttle body and intercooler are almost always the solution. However, when the problem persists after all that, and no codes are displayed, the turbo boost regulator valve should be checked if it is working properly. As time goes by and they get old, they start losing the force required to manage the turbo boost (I think they work by creating vaccuum). The part in question is right on top of the engine, and its one of the first things you see when you remove the engine cover. It's on a metal bracket.

Quite an expensive part, if bought new, so before replacing, clean all the intake.
