you will need to get someone to pull the codes , either the dealer or go to autozone and they can pull them . You can also pull them via the MIL by doing the keydance , ignition on, off , on off , then on and count the flashes , a flash a pause then 2 flashes equals 12 , when it is finished you will get a 55 code.

What is said is that your car has the ability to check itself by use of the service engine soon (SES) light. You put the key in the ignition and then turn the key to ON (not start) then back to off, then back to on, and then to off, and finally to on and then off and wait (do not remove the key at any time until after the test iws done). Your SES will start to blink, count the number of blinks (it works like this ,one blink and a pause, two blinks and a pause is a 12) count all of these dcodes until a code 55 which is end of test and let us know what numbers you get and we will tell you what the numbers mean. In the USA we can go to Auto Zone and they will do this code on a machine and give us a print out (and it is free).

I apologize, the sequence is Key On, Key Off. Key On, Key Off and then Key On. The iginition must be in the ON possition to obtain the codes

91 (hihg air flow) manifold presssure signal does not relate to throttle position. Check for a vacumn leak or broken manifold.
