What does a trouble code p2097 mean?
Anytime that I come across a trouble code P2097, I know means that the powertrain control module (PCM) has detected a signal voltage input from the downstream (post catalyst) oxygen (O2) sensor for engine bank one that indicates the oxygen particle content is too low. Bank 1 is the engine bank that contains the number one cylinder.
When did my Mazda 3 p2177 come on?
Mfg 03/06. 100% stock (no CAI or any of that nonsense). Let’s go back about 8 months. CEL came on at around 120,000 miles, yielding a P2177 code (System Too Lean Off Idle Bank 1). No discernible issues beyond the code. I’d reset it either via a scanner or by disconnecting the battery, only to have it return anywhere from 60 to 150 miles later.
What does diagnostic trouble code DTC stand for?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, etc.). Although generic, the specific repair steps may vary depending on make/model.
What does p2097 mean on post catalytic converter O2 sensor?
A P2097 code means that the post catalytic converter O2 sensor has detected a rich exhaust condition. Fuel efficiency may be compromised and the code should be addressed as severe.

What causes the p2187 DTC system to lean at idle?
Potential Causes of P2187 DTC. Air leaking into the intake manifold downstream from the Mass Airflow sensor due to the manifold itself, vacuum hoses off or cracked, leak MAP sensor, Leak at turbo bypass or it’s stuck open, power brake booster hose, or a leak in the EVAP system hoses.
What is the error code for Mazda 3 TCM?
Error P0884 – TCM Power Input Signal Intermittent (Gearbox electronic control module (TCM), input power signal – unreliable pin of the electrical circuit) Error P2709 – Shift solenoid valve manifold “F” Electrical (electromagnetic valve F gear switches – electrical malfunction)
What causes a p2187 code leak in the exhaust system?
Additional codes to pinpoint cause of original P2187 code Air leaking into the intake manifold downstream from the Mass Airflow sensor due to the manifold itself, vacuum hoses off or cracked, leak MAP sensor, Leak at turbo bypass or it’s stuck open, power brake booster hose, or a leak in the EVAP system hoses.
