P1400 No decription available

Back again with more problems.

code: P1400 NO DECRIPTION AVAILABLE

I still cant get my car to pass the freakin CA smog test. The only thing making it fail now is this P1400 engine code. I cant find the problem. The tech. is saying that the CEL wire has been bypassed.

Anyone know what can it be? YES, i've search and cant find my problem.

please let me know
Thanks

P1400 Manifold Differential Pressure Sensor Circuit Malfunction

Try replacing the sensor

^^HOLY CRAP, man...


Don't replace the sensor, that is retarded.... TEST the sensor by following the Factory Service Manual's procedures...

THEN if it is not the sensor, start checking the harness to the sensor for shorts or breaks in the wire.

Throwing money at your car by just assuming that the CEL is a mechanic diagnosing your car is NOT the way to troubleshoot problems.

I dont think the book states how to test the resistance on that particular sensor.. That is why I said replace it.. Unless, you know the ohms it should read?

 

[bling5tatus]

What book are you talking about? Because if it's haynes or chiltons, then I would understand the incompleteness of the information.

 

[93_tsi_fwd]

can someone tell me where the Manifold Differential Pressure Sensor is located?

thanks
