I just ordered my mafs at Jagparts.com the cost was $76.33 free shippig and no sales tax. I also ordered the Bosch DCCV at the same time.

 

Why did you buy a MAF?

 

Thanks and agree with the hose removal, Sivkov-y, and thanks for the online source, Larry.

I still have the CEL and I am at a loss, thinking about going to the dealer since its still under warranty, and please share your thoughts.

Spent the weekend swapping 3 MAF sensors, running the codes and then resetting the CEL, here are the results:

1) OEM MAF Sensor

1st instance
Code P0174 - Lean banks 1 & 2
Ltft 13.3 b1 / 19.5 b2
Stft 0.8 b1 / 3.9 b2
CEL / Poor fuel economy (less 50 miles, 250 vs 300)

2nd instance
Code P0174 - Lean bank 2
Ltft 14.1 b1 / 19.5 b2
Stft 1.6 b1 / 4.7 b2
CEL / Poor fuel economy (less 50 miles, 250 vs 300)

3rd instance
P0174 b1 / b2 - System too lean
P0171 b1 / b2- *Lean banks 1 & 2
Ltft 15.6 b1 / 19.5 b2
Stft 5.5 b1 / 9.4 b2
CEL / Poor fuel economy (less 50 miles, 250 vs 300)

2) eBay MAF Sensor

1st instance
Code P0101 - MAF circuit
Code P0174 - Lean bank 2
Ltft 17.2 b1 / 18.8 b2
Stft -25.8 b1 / -25.0 b2
CEL / Woomp hesitation / exhaust backpressure and loss of power on acceleration;
Poor fuel economy (less 50 miles, 250 vs 300);
High rev 4K rpm before shifting;

2nd instance
Code P0101 - mass or volume airflow circuit range/performance
Ltft *10.2 b1 / 13.3 b2
Stft -15.6 b1 / -15.6 b2
CEL / Woomp hesitation / exhaust backpressure and loss of power on acceleration;
Poor fuel economy (less 50 miles, 250 vs 300);
High rev 4K rpm before shifting;

3) Autozone *MAF Sensor

1st instance
Code P0101 - MAF circuit
Ltft 14.8 b1 / 18.0 b2
Stft -22.7b1 */ -22.7 b2
CEL / Woomp hesitation / exhaust backpressure and loss of power on acceleration;
Poor fuel economy (less 50 miles, 250 vs 300)
High rev 4K rpm before shifting;

2nd instance
Code P0101 - MAF circuit
Ltft 14.1 b1 / 17.2 b2
Stft -29.7 b1 / -28.9 b2
CEL / Woomp hesitation / exhaust backpressure and loss of power on acceleration;
Poor fuel economy (less 50 miles, 250 vs 300)
High rev 4K rpm before shifting;
Billowed black smoke from exhaust upon initial acceleration;

 

Reading anoother post, it sounnds like it could be an O2 sensor too. My question is why such a variance on the replacement MAF sensors?

I will also share that I will not order parts from eBay or Autozone again for this car.

In my mind, service at the dealer is the way to go to help resolve this since its still under warranty.

 

YOu mentioned that you know someone who sells the MAF for the STR, so like whats the price and brand of it? I'm in the market for one, so deciding on where to source a good quality one out with buying a brand new one.

Thanks.

 

Damm the price is $111.79 now plus the core charge of $70, lolz..looks like every year its going up

I see that the A1 Cardone which RockAuto has is a lot cheaper on Ebay......
