Folks, thanks to your suggestions I ordered a blue driver OBD 2 reader and plugged it in to my '97 F355 spider. Not the easiest spot to reach. Received the following codes: Confirmed trouble code- PO154 02 sensor circuit- no activity detected Bank 2 sensor 1 5 Pending trouble codes 1) PO134 02 sensor circuit- no activity detected Bank 1, sensor 1 2) P1119- no description 3) P1451- no description 4) P1126- no description 5) P1448- no description #1 assuming that the bank 2 leading O2 sensor is bad and because of this, pending on the other bank ? Can anyone decipher the other codes ? really appreciate your help, best, Jon Final question...have had Italian cars including my Dino for over 25 years. How does one evolve their status from Rookie. Thanks and cheers
As far as I can tell, it's purely based on the number of posts you make on the forum. I guess a "contribution scale"... although some posts are more contributive than others Regarding the codes: 2) P1119- Bank 2 upstream O2 sensor heater circuit 3) P1451- Secondary Air Pump circuit (short to ground (min))/ Not present 4) P1126- Long term fuel trim additive air (bank 2), system too lean, check fuel pressure, check HX CO emission with no lambda integrator, check injector and wiring, check ignition coil and wiring, check exhaust system leakage. 5) P1448- Catalyst bypass flap circuit, malfunction, check wiring, check the valve, check vacuum leakage.... An interesting combination of problems. Do you have a standard exhaust system? Has someone been playing with your car recently? Major? Re: 2) P1119- Bank 2 upstream O2 sensor heater circuit. I don't think this is a fuse or relay problem as it would register as four O2 sensors failing (I'm assuming you have a 5.2 engine management system). It may just be the left bank forward sensor itself that has failed. You can check for voltage going to the sensor (with the ignition turned on). O2 sensor plug (car side) wiring colours vary on these cars, but the O2 sensor heater wires are probably white. Just find the corresponding wires on the car side of the plug. Re: 3) P1451- Secondary Air Pump circuit (short to ground (min))/ Not present. I don't understand this at all. Maybe it's a F360 code. The engine ECU on the F355 has no feedback from the power circuits of the secondary air pump. At best, it can only monitor the secondary air pump relay solenoid or the effect of the secondary air pump not working. It's relay "L" in the passenger footwell according to the drivers handbook (or E10 as it is identified on the relay panel itself). When the engine is warming up, can you feel/hear the pump operating? Re: 5) P1448- Catalyst bypass flap circuit, malfunction, check wiring, check the valve, check vacuum leakage.... Lots of things to check here. Sometimes the electrical plug on the bypass solenoid valve is swapped over to the adjacent secondary air solenoid valve. You will need wire colours to identify the right plugs. Re: 4) P1126- Long term fuel trim additive air (bank 2), system too lean, check fuel pressure, check HX CO emission with no lambda integrator, check injector and wiring, check ignition coil and wiring, check exhaust system leakage. Lots to check here, too. Having a sensor heat problem on the same bank (left) makes me think the plug on the foward O2 sensor has fallen off or is damaged or the sensor itself is damaged. Let us know if you need further elaboration or simplification or wiring diagrams
I think you should ignore the pending codes for now and focus on the actual code 0154. Solve that, clear all codes, and see what comes back. You have no idea how old those pending codes are.
Thank you to everyone who responded to my fault code questions. Ian from Sydney gave such a thorough response, much appreciated !! As with any new car I bring in, takes a little while to get everything settled. I have asked for the engine out menu from my nearest Ferrari service center so that i can compare with the work actually performed, then will work to clear the O2 sensor, and as advised clear codes and see what then pops up. Car drives like a bomb and is so incredible responsive. Thanks to everyone for your timely response on this issue. stay safe and all the best, Jon
@yelcab and everyone who has been of great help. I ordered and received the forward Bosch oxygen sensor # 13819...the rear sensor is # 13820 and considerably less expensive. I do like the idea of purchasing the "generic' sensor and soldering it in, but as I am running with a bit of trepidation here, will go this rout. As I am behind the car which bank is bank 1. My fault code PO134 is for bank 1 sensor 1...is this the drivers or passengers side ? I reviewed earlier posts and unfortunately this was called out for both sides. Once I have swapped in the part, how does one then clear the fault codes, so that the dreaded CEL will turn off. Will this simply be a function of the ECU ? And one more small request. My ABS light intermittently goes on and off. Any suggestions here ? My 355 Spider goes like a bomb, yes it is a 5.2 car with 4 oxygen sensors. I am looking forward to returning these information favors as I become more familiar and confident. All of my other classic cars are strictly analogue and therefore easier to diagnose. This is the most complicated platform I have owned yet and want to do it right. Also one of the best owners manuals I have ever seen. Thanks again to all and enjoy this marvelous springtime weather !! Cheers.
For a US car, bank 1 is the side without the steering wheel. You reset the ECU using the OBD II reader. The instructions that came with it should tell you how.
Bank 1 is the right hand side looking forward, so the passenger's side on US cars. Sensor 1 is the forward one. I don't know if your CEL will extinguish automatically, but all OBD2 readers should have the ability to erase old codes (and extinguish the CEL). ABS problems may be caused by dirty wheelspeed sensors.
CEL will not clear itself even if the disconnect the battery. Use your OBD2 clear DTC code function to clear the error codes. See if you can read the ABS code, otherwise not very much can be said.
Two new oxygen probes forward installed in my '97 355 spider...that was fun and a good education for me. Codes cleared...check engine light is off, rechecked, no fault codes...drove the car on my 20 mile mountain course, ABS light went off and stayed off.... while i am somehow waiting for the other Ferrari shoe to drop, life is good, car is wonderful. Thanks again to everyone for their comments. Took me 7 hours to r/r the oxygen probes, first under the car, then back in the engine bay, then under again. I am sure that this was probably 3 times as long but I was going at snail speed, photographing and placing fasteners in specific orders, etc. You guys rock !! Good weekend !!
