P0340 code need help on 97 t-bird v6 3.8L engine
Hello and thanks for reading my post,
I live in Texas and now an emissions test is now part of the process to renew your inspection sticker. According to the inspector if your check engine light is on for any reason, the test is an automatic fail. Well my check engine was light for the following codes:
P0340 - camshaft position sensor a bank 1 circuit malfunction
P0131 - o2 sensor circuit low volts (bank 1 sensor 1)
P0133 - o2 sensor ckt slow response (bank 1 sensor 1)
P1131 - insuff. switching control valve sensor / lean
P0171 - system too lean.
Not having replaced the o2 sensors ever I started there. (I know, I know I've been slacking but this car has been really good to me with no problems whatso ever since I purched in 97.)
I've done three of the four (ouch that hurt my wallet $$, why couldn't it just be two sensors) I still need to replace one as the o2 sensor i was given at an auto parts store did not fit. The cord was too short. I believe the one I still need to replaced is located on the passenger side in front of the catalytic converter.
first question, IS THIS THE BANK 1 SENSOR? After replacing that one I'm hoping it will clear up all or some of these codes.
Second question is regarding the p0340 code. First, where is the sensor located on the 97 3.8L engine? Will replacing the sensor more than likely fix the problem?
Any help / suggestions on these codes are greatly appreciated as I gotta get the inspection passed on this vehicle.
FYI, the car is running even with all these codes.
