Some scan devices will register the codes marked by (*)

What Does The P2097 Error Code Indicate?

The P2097 error code signifies that the Powertrain Administration Module (PCM) has flagged a ‘lean’ or ‘rich’ scenario from the post-catalyst oxygen sensor(s). A lean scenario means there could also be an excessive amount of air post-combustion. A rich scenario signifies an excessive amount of gasoline post-combustion. On most engines, a lean scenario could possibly be flagged by the post-combustion air/gasoline sensor and set the P0171 code, whereas a rich scenario normally items the P0172 code.

Nonetheless, distinctive to the Chevy Malibu is the post-catalyst fuel-trim monitoring. This monitoring makes use of the post-catalyst oxygen sensors. That is the rationale the P0171 or P0172 error codes may not be set, nonetheless P2097 will. The P2097 is about when the air/gasoline ratio prohibit has been exceeded, each by a ‘lean’ or ‘rich’ scenario.

It’s important to know that the P2097 code would not immediately level out the engine is working rich, whatever the code title displayed on positive scan devices.

What Causes The P2097 Error Code?

Aftermarket Parts

Not all automotive components are created equal; not lower than, they won’t be equal to GM’s Distinctive Gear (OE) necessities.

The TSB states that the gasket normally would not require various and solely the bolts must be torqued to the manufacturing unit specification, which is 12 Nm or 108 in-lbs.
