Topic: 22 re codes?? what do they mean?

[dov'd85]

checked my computer and it gave me 2 blinks 4blinks 7 blinks and 8 blinks what do these mean and what sensors need to be replaced?

You need to pay attention to the blinks, and the spaces between the blinks.  Two blinks, short space, and four blinks  would be a 24 code.  Then, if there is a long space, it means the start of the next codes or the start of repeating the first code.

the codes are 2 seconds apart. they are 4 seperate codes...

[Uncle Jesse]

I don't believe that there are any numbered codes below 11

[dov'd85 [OP]]

in the book it tells me codes 2 4 7 8. are 2 blinks airflow meter siglan    4 blinks  waterpump thermo sensor    7 blinks throttle position sensor signal
8 blinks intake thermo signal

then it gives a list of trouble area's i want to no what sensors would most like be the ones for thes codes....
were would i go to get a thermo sensor and what is the intake thermo signal? and the air flow meter signal?
thanks

The intake air temp sensor is inside of the air flow meter.  The water temp sensor is on the lower intake, approximately below the thermostat housing.

what is the sensor right before the thermostat?
