Recall - (MAF Sensor) Low Speed Stalling: Overview

Group: CAMPAIGN

Number: 00-01-005

Date: OCTOBER, 2000

Model: 1999-2000 SONATA

Subject:
1999-2000 SONATA V-6 MASS AIR FLOW SENSOR CONNECTION CAMPAIGN 039

DESCRIPTION:
Engine vibration transmitted to the MAF (Mass Air Flow) sensor electrical connector wiring harness may cause an intermittent MAF sensor electrical signal interruption, which may lead to low speed engine stalling on some 1999 and 2000 model year Sonata vehicles equipped with 2.5-liter V-6 engines. The MAF sensor connector wiring harness is secured to the air intake resonator on vehicles produced through May 29, 2000. The following procedure reduces the vibration transmitted to the MAF sensor connector by changing the sensor wiring routing and mounting position from the air intake resonator to a new air intake hose clamp.

In addition, the MAF sensor connector female terminal pins will be packed with corrosion inhibiting grease and the ECM (Engine Control Module) on all 1999 and 2000 model year Sonata vehicles equipped with 2.5-liter V-6 engines will be reprogrammed, using the Hi-Scan Pro, with new logic to reduce the likelihood of low speed stalling if a MAF sensor signal interruption occurs.
