1997 850 P0422 code issue

Post by asims » Wed Feb 20, 2019 8:35 am

Greetings and good morning, I have a 97 Volvo 850 and reviving the following code: PO422, which the check engine light came on. I replaced both O2 seniors and the check engine went off. However, I am receiving the POP22 code. I received the following on my diagnostic device "Fuel system status: Closed loop, using oxygen sensor feedback to determine fuel mix Calculated engine load: 22.0 %, Engine coolant temperature: 159.8 F, Short term fuel trim—Bank 1: 0.0 %, Long term fuel trim—Bank 1: 6.25 %, Engine RPM: 2120.0 rpm, Vehicle speed: 21.11 mph. With the figures shown on my Short term fuel trim and Long term fuel trim". Could this be a valium leak, wiring or my catalytic converter? Please Help.

Thank you,
asims
