Greetings ladys and gents , Recently picked up a 1999 Targa , Love every Inch and sound of her , I do find she rides a little harsh , I gather thats due to the sloppy roads we have here In Montreal Quebec and the C5's leaf springs.
When I purchased the car every thing seemed fine , Apart from the minor stone chips , After a week of having her I came across a check engine light , Using the Innova 3100 obd2 scanner , She read as follows
0P140 Secondary Injection system.
Has or does any one have an Idea as to what this may be ?
Should I be worrying ?
Ps on another note , Went for an oil change and I was told to use reg oil , where as Ive read that syntec Is required ?
Don't know about your injector issue but use synthetic oil. Do not put reg oil in it. Mobile 1 is recommended and when in doubt use what they recommend. Or even if you're not in doubt. I use valvoline myself but it's on the approved list. Others use royal purple, but always use synthetic.
Do an "Advanced Search" above on the OBD code, covered many times. You also do NOT need an OBD scanner, you can get most all the OBD codes via the dash (again use the search function on OBD codes above).
After a week of having her I came across a check engine light , Using the Innova 3100 obd2 scanner , She read as follows
0P140 Secondary Injection system.
The code (I'm assuming P0140) and the given description is not correct.
A P0140 is for the Bank 1 O2 sensor, position 2.
A P0410 is for the secondary air injection system.
Thanks for the freeB I was able to resolve the Issue ! Following the the post you gave me I read that Relay#33 and #40 each play a role , And the common Issue Is that one of the 2 relays Is non functioning , I was able to test each relay using the horn relay (Note to self bye an om amp) Drove her for a good 45 mins and the check engine light never came up.
