What Goes Wrong

Signs that something has gone wrong may include poor general performance, poor idle quality, lack of power, black smoke from the exhaust, poor fuel economy, DTC etc.

The major cause of Mass Air Flow Meter (MAF) premature failure is contamination of the hot wire/sensing element. Airborne contaminates passing across the hot wire or sensing element accumulate over time. This contamination may come thru the air filter while the engine is running, oil contamination from oil fumes remaining in the intake manifold or left over EGR residue. This contamination effects the MAF’s ability to accurately determine the air flow.

Later model MAF’s changed their design to reduce the effect of airborne contaminates. The amount of air flowing across the sensing element was reduced as well as design changes allowing the heavier contaminant particles to bypass the sensing element. Although this improved the contamination problem it did not eliminate it.

Note: The use of reusable oiled air filters that have been over-oiled can often be the cause contamination.

Diagnostics

MAF signals are best looked at with an appropriate Scan Tool or Oscilloscope at varying engine speeds and compared with a known good signal or manufacturer’s specifications. Diagnostic trouble codes will be set by a faulty or badly contaminated MAF. Typical DTC’s associated with MAF faults include but are not limited to,

P0068 – MAF Fault
P0100 – MAF Fault
P0101 – MAF Range/Performance
P0102 – MAF Voltage Low
P0103 – MAF Voltage High
P0104 – MAF Circuit Intermittent

It is important that a technician diagnosing a vehicle for a suspected MAF fault does not forget to check the simple things. Leaks in the air induction system or intake manifold can cause the MAF sensor to give false readings. Faulty wiring and electromagnetic interference from the ignition system can also effect the signal to the ECU. Output voltages and frequency specifications differ depending on application and the type of MAF used. Always refer to manufacturer specifications and procedures.

When you supply and fit products from VOLTSTEC you can expect a product designed and tested to the vehicle manufacturer’s specifications offering OE form fit and function.
