Today I got my first CEL appear. I read the codes using the flashing light method, and got the following:
P0139 O2 Sensor Circuit Slow Response (Bank 1 Sensor 2)
I'm assuming that 10 slow flashes after that code mean its the only code that is current, and the ones after are old stored codes?
I think the next codes were
P0159 O2 Sensor Circuit Slow Response (Bank 2 Sensor 2)
P0146 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 3)
P0166 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 3)
P0147 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 3)
P0167 O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 3)
then the 10 slow flashes again.
So I might be jumping to a conclusion here, but these would be due to having the Berk HFC's fitted 500 miles ago?
Would they have been caused by disconnecting the lambda sensors, or do I need the spacers from Zmanalex?
(I thought it was only decats that needed these?)
And lastly, could I cause damage by driving with the check engine light on, if it comes back?
Cheers
