- Courtesy inspection
- Scanned for fault codes: P0157 – HO2S B2S2 low voltage, P0300 -Engine misfire detected, P2271 – HO2S B1S2 signal stuck rich. Sensors have been replaced recently and are reading correctly currently. Smoke tested to check for air leaks in intake tract, none found. Unable to lift vehicle to check underside of vehicle for possible exhaust side leaks. Condition is very intermittent according to customer. Suspect either an air leak in exhaust causing sensors to skew or an air leak in intake side causing lean air/fuel mixture. Third possibility is a software or computer glitch. Would need to be able to capture data while vehicle is acting up to further pinpoint cause.
